Bloodline: Heroes of Lithas is a mobile Gacha-RPG game for Android and IOS, published on June 22nd, 2022 by Goat Games.
The game centers on a light vs dark storyline, centered around the player's in-game avatar called the High Guardian; the newly appointed ruler of the city of light.

The High Guardian takes an active role as a character in the plot of the story, leading groups of Champions through the storyline to restore peace to the world of Lithas, and undo an evil conspiracy that has turned the peoples of the land against one another. In pursuit of this goal, the player has to acquire or recruit champions by summoning them randomly from the summoning circle, recruiting imprisoned hostile champions, discovering champions by exploration, or producing new champions through courting companions and raising their heirs. With companions being slowly accumulated from summoning or exploration, or quickly acquired from events and rewards. Champions are divided into clans that are then separated by gender to produce the multitude of varieties, and come with a variety of ranks and rarities that determine their power and number of traits.
Champions can then be upgraded in a number of ways, and given upgradeable equipment to help them fight against stronger and stronger enemies, until the only way to overcome is to produce progenies with better traits through the marriage system, which then retires the married champions in exchange for the progeny.
