Son of Sanadhìl Órecalo and Arek. Their first child, second eldest in the family. Xan's is a mixed bag of human, Cozovodë, and whatever Arek is: he was born with wings, but he can change his shape at will and generally disguises them. He followed in his father's footsteps, studying San's particular brand of enchantment magic, and started a business as a professional researcher/explorer.
Xandhil is seriously (but not exclusively) romantically involved with Justen Olivier. He also has a daughter with Mercy Olivier, Solange Olivier, but they are not and have never been romantically involved - she just asked him to help her have a baby.
