The dnd campaign that I play Aster in is set in Ancient Greece, and Kalister came from a faun tribe that roamed around the area that would eventually become Germany and Central Europe. Fauns (in this lore) can create magically shrouded Groves to protect themselves if they're in danger, but when Kalister's tribe was threatened, the enshrouding failed and she was left alone. They eventually married the brother of the hunter that killed their family, but had to leave their child at the divine faun city of Altar to protect her when their husband was killed too.

Kalister is, to put it simply, an asshole. She hates most other people and even when she likes someone she would never tell them that. Every time they're moved to help other people, it's motivated only by what they get in return; and all they truly care about is taking down the hunter that killed her tribe.
