Species: asari
The asari, native to the planet Thessia, are often considered the most powerful and respected sentient species in the galaxy, and are known for their elegance, diplomacy, and biotic aptitude. This is partly due to the fact that the asari were among the earliest races to achieve interstellar flight after the Protheans, and the first to discover and settle the Citadel.
A mono-gender race, the asari are distinctly feminine in appearance and possess maternal instincts. Their unique physiology, expressed in a millennia-long lifespan and the ability to reproduce with a partner of any gender or species, gives them a conservative yet convivial attitude toward other races. Favoring compromise and cooperation over conflict, the asari were instrumental in proposing and founding the Citadel Council and have been at the heart of galactic society ever since.
Biology
A typical asari individual has a blue to purple complexion; the gas giant Sharblu was named after a famous asari soprano with a distinctive skin tone that resembled the planet's atmosphere. Some asari can also have a teal complexion, but this seems to be a rarity. Some asari, such as Matriarch Lidanya, Matriarch Benezia, Liara T'Soni, and Tela Vasir have facial markings, which are unique color patterns that vary for every asari. Some of these facial markings are associated with eyebrows by humans, but the asari do not think of the markings as such themselves. In the place of head hair, asari possess semi-flexible, cartilage based scalp crests that grow into shape. These structures are rigid, and do not "flop around" as some believe. Asari also have a robust cellular regenerative system; while they do not heal faster than other species, they are known to reach over 1000 years of age. Asari blood is purple.
Uniquely, the asari are known to be perceived as attractive to many other species. At the Eternity bar, a conversation occurs between a human, a salarian, and a turian who are watching an asari dancer. The men debate whose species the asari most resembles. Upon each forwarding their own race, the human theorizes that the asari might be using mind control to appear attractive to other species, but it is more likely that the three men were merely focusing on characteristics their species shares with the asari (e.g., body shape for humans, skin color for salarians, head fringe for turians). All three men compliment the asari's flexibility and grace. This conversation implies that asari are considered attractive to many species, which would prove useful considering their method of reproduction. Mordin Solus postulates that the mechanism behind the asari's cross-species attraction may be neurochemical in nature.
There is some conflicting information regarding the gender of the asari. Though they resemble females, at least to humans, asari are non-gender specific, with no concept of gender differences. Liara says her species is "mono-gendered—male and female have no real meaning for us," and, if asked, says that she is "not precisely a woman". Despite this, the Codex states that the asari are an all-female race, and the Galactic Codex: Essentials Edition 2183 explains that "while asari have only one gender, they are not asexual like single-celled life—all asari are sexually female".
However asari gender is defined, they are innately different from humans, for asari can mate and successfully reproduce with any other gender or species. Although they have one gender, they are not asexual. An asari provides two copies of her own genes to her offspring, which is always an asari, regardless of the species or sex of the "father", and in the case that the offspring is of two asari, the father is the one who does not give birth. The second set of genes is altered in a unique process called melding, also known as the joining.
During melding, an asari consciously attunes her nervous system to her partner's, sending and receiving electrical impulses directly through the skin. A common phrase used before melding is "embrace eternity," presumably to help focus the partner's mind. Effectively, the asari and her partner briefly become one unified nervous system. This unique means of reproduction is the reason asari are all talented biotics. Their evolved ability to consciously control nerve impulses is very similar to biotic training. The partner can be another asari, or an alien of any gender. However, since the asari began encountering other sentient species, non-asari mates have become preferred for the diversity they provide. This reproductive process can lead to some confusion among non-asari, who might expect offspring with "mixed" genes. However, the offspring is always 100% asari as no DNA is taken from the partner, but is rather used as a "map" to randomize the genes of the offspring.
An asari's melding ability extends to a mental connection as well, which Liara describes as being the true union between an asari and her partner. It allows the asari to explore her partner's genetic heritage and pass desirable traits on to any offspring. During mating an asari and her partner share memories, thoughts, and feelings. It is also possible for an asari to meld with another for the sole purpose of transferring thoughts, without reproduction. This technique is used by both Liara and Shiala, with varying success; Liara finds the ordeal extremely intense and debilitating.
Asari pass through three climacteric life stages, marked by biochemical and physiological changes:
The Maiden stage begins at puberty and is marked by the drive to explore and experience. Most young asari are curious and restless, and it is not uncommon for many to try their hand at dancing in bars or working as mercenaries during this time.
The Matron stage of life begins around the age of 350, though it can be triggered earlier if the individual melds frequently. This period is marked by a desire to settle in one area and raise children.
The Matriarch stage begins around 700 years of age, or earlier if the individual melds rarely. Matriarchs become active in their community as sages and councilors, dispensing wisdom from centuries of experience. Their knowledge and guidance may be one reason why Matriarchs are rarely seen outside asari space.
However, it should be noted that each stage can be started whenever an asari feels that she has reached the correct level of maturity. While each stage of life is marked by strong biological tendencies, individuals do make unexpected life choices. For example, there are Maidens who stay close to home rather than explore, Matrons who would rather work than build a family, and Matriarchs who have no interest in community affairs.
Origins
The asari arose on Thessia, a rich world with abundant quantities of element zero that caused much of life on Thessia to exhibit biotic tendencies. Instrumental to the rise of asari civilization was the intervention of the Protheans. Upon discovering the asari, the Protheans crafted the guise of Athame, a benevolent goddess who imparted gifts of wisdom to the asari through her guides Janiri and Lucen, a deception that allowed the Protheans to rapidly accelerate asari development. The Protheans also genetically altered the asari to grant them biotic capabilities, and defended Thessia from an asteroid strike and the resource-hungry oravores.
When the Protheans departed, they left a single beacon on Thessia, around which the asari later built a lavish temple devoted to Athame. This beacon contained Vendetta, a Prothean VI, and over the following centuries was the source of countless technological advances that allowed the asari to eventually become the most powerful race in the galaxy. The beacon's existence became a closely-held state secret, as its revelation would have discredited the virtually universal belief that the asari attained such heights on their own merit. By 2183 CE, few outside the highest echelons of the asari government were aware of the part the Protheans played in asari history.
Culture
Because of their long lifespan, asari tend to have a "long view" not common in other races. When they encounter a new species or situation, the asari are more comfortable with an extended period of passive observation and study than immediate action. They are unfazed that some of their investments or decisions may not pay off for decades or centuries. Matriarchs can seem to make incomprehensible decisions, but their insight is evident when their carefully-laid plans come to fruition. In interstellar relations, this long view manifests in the unspoken policy of centrism. The asari instinctively seek to maintain stable balances of economic, political, and military power.
Traditionally, asari spread their influence through cultural domination and intellectual superiority. They invite new species of advanced development to join the galactic community, knowing that their ideals and beliefs will inevitably influence the existing culture. The asari tend toward communal, consensus attitudes among themselves too: for example, they prefer to live in shared spaces aboard starships even if there are alternatives available.
Asari believe that their offspring acquire the best qualities of the "father" from the melded genes, but evidence is anecdotal. They frown upon intraspecies conception, since genetic traits and cultural insight is gained from mating outside their species, so it's considered wasteful for asari to reproduce together. The results of such unions are occasionally referred to as "purebloods", a great insult among contemporary asari. A rare genetic defect known as Ardat-Yakshi, which makes asari destroy the partner's mind during melding, occurs much more frequently among the daughters of purebloods.
Asari are well aware they tend to be attractive, and are comfortable expressing their sexuality, as can be witnessed in places like Chora's Den or Afterlife with asari erotic dancers. Young males of other races tend to have a fascination with asari. Kaidan Alenko mentions that the sight of Matriarch Benezia in a pin-striped suit sounds like something from an extranet fetish site. David Anderson admits that, when dealing with the asari, their feminine appearance makes it difficult for him to accept them as one of the most powerful races in the galaxy despite their political and military prowess, but he feels that this isn't his fault due to thousands of years of human cultural bias.
Because of their natural sensuality and ability to mate with any species, asari are sometimes rumoured to be promiscuous. These rumours are mostly a result of misinformation (or wishful thinking). In fact, asari have to accept that if they mate outside their own species, they will almost inevitably outlive their partner (with the notable exception of the krogan, who have a similarly immense longevity). Therefore, they have had to apply their philosophical "long view" to relationships as well, savouring the time they spend with their partners rather than focusing on their inevitable loss. On the Citadel, an asari and her turian companion are trying to decide on a souvenir to purchase, and while her friend feels a fish is too short-lived to make a good memento, the asari notes that they must "enjoy the time they have with the fish." Also while browsing at the Memories of Illium kiosk on Illium, an asari and her salarian step-father are trying to decide on a memento to purchase for her mother. As a result of the age difference many asari raise their daughters alone, especially if the "father" species is short-lived. Despite their partner's death, a part of them will live within their other.
The asari celebrate the springtime fertility ritual Janiris, named for the goddess Athame's guide Janiri, which marks the start of the new year. During this time, they create wreathes of flowers and distribute them among their friends and loved ones. As is the case with the holidays of some other Citadel species, the celebration of Janiris has been adopted by other species that operate in Citadel space.
A few asari abandon all but a few personal possessions to become justicars, members of an ancient order of asari adhering to a strict code. Justicars operate inside of asari space correcting injustices, often through harsh means, including death. It is rare for a justicar to leave asari space as it could cause a diplomatic incident with other species.
Religion
The pantheistic mainstream asari religion is siari, which translates roughly as "All is one". The faithful agree on certain core truths: the universe is a consciousness, every life within it is an aspect of the greater whole, and death is a merging of one's spiritual energy back into greater universal consciousness. Siarists don't specifically believe in reincarnation; they believe in spiritual energy returning to the universal consciousness upon death will eventually be used to fill new mortal vessels.
Siari became popular after the asari left their homeworld and discovered their ability to "meld" with nearly any form of life. This ability is seen as proof that all life is fundamentally similar. Siari priestesses see their role as promoting unity between disparate shards of the universe's awareness.
Before the rise of siari pantheism, asari religions were as diverse as their political opinion. The strongest survivor of those days is the monotheistic religion worshipping the goddess Athame. Like the asari, the goddess cycles through the triple aspects of maiden, matron, and matriarch. Asari often swear "by the goddess", though this may be a cultural legacy rather than reflecting an individual's belief.
