From the commissioner:

You meet all kinds of interesting people, and Forestwalker's interaction with the people of Equus led hir to meet Citrine, a crystallomancer. A little experimentation later and Forest has a new toy. The artificial horn lets hir use telekinesis, much to the surprise of a passing crewmember.
