People have always been scared or awed by you. Or they came with pitchforks. You remind people of times long-past, and the demons that supposedly walked on the world.
You found out long ago it was usually best to keep to yourself. Begging and thievery might have been in your past; you might have been a gypsy. Or, its possible you found "work" as a mascot or good luck charm to some wealthy patron. If you were able to keep your head down and keep to yourself, it's possible you found work in a human town.
Ptolus may be one place where you get few strange looks. They have seen many types of beings in that city, and your appearance might barely be noticed. You could seek your fortune there, and potentially even own property and settle down. Or, you could research into your heritage ... Ptolus is said to have demons that walk the streets this very day.
