Raised in a well off Teifling family Clarice went to university to study history and religion. In her studies she gained an appreciation of peoples, cultures and magics - developing her goal to explore the world and use her people skills to immerse herself fully in cultures on the way. Her disregard for her family expectations and traditional roles with her less than academic pursuits tarnished the family name who valued their bloodline. Her insistence on having "dalliances" with species that would disgrace this has led to her being cut off from the family finances and support - they haven't quite resorted to saying she is dead yet but she is aware that she is only a few drinks and questionable decisions away from it and this has not stopped her yet.
In Clarice's new journey of independence (aka estrangement) she used her charm and wisdom to scrape a living doing odd jobs and on her travels came across followers of the Free Gods. In her "cultural immersion" she found herself falling for the goddess Avandra and consequently becoming a devoted follower. Avandra's domains of change, freedom and luck spoke to Clarice's rebellion from her family and desire to take her fate into her own hands. The goddess' symbol is 3 horizontal wavy lines which she wears this on bracelets on her wrists.
Clarice now continues her pursuit for knowledge and experience while also pushing for positive change in the world trusting her luck and fate with her God. She is using these teachings to justify her nomadic lifestyle and is going through life on vibes - how she ended up in this party is probably just as a surprise her as it is to everyone else. Expect, perhaps, her family, who of course are disappointed in her.
