History:
Tanvi doesn't remember much about her birth parents. She only knows bits and pieces, the brightness of their smiles, their love of dance, her mother's perfume, but little else. She was adopted by Ishaan Arya, a high-ranking member of the Radiant Host, and Honored Willow, an alchemist at the Great Work, and their daughter, Aditi Arya. When Tanvi grew older, in an attempt to prove herself as an alchemist, she journeyed to Ul'dah to join the Alchemist's Guild and continue to improve her craft.
Hooks:
Alchemist: Tanvi is a practicing alchemist. While not a very skilled magical healer, she often has tonics and potions to help manage symptoms and various ailments and works at the Alchemist's Guild in Ul'dah during the day. Perhaps you work with her or have commissioned her in the past. Maybe you're a botanist she contracted for rare ingredients.
Student in Old Sharlayan: She is currently studying Alchemy in Old Sharlayan. Perhaps you've seen her around there, nose buried in a book or participating in a study group.
Fight Arena waitress: Responsible for serving and seating guests, Tanvi sees a lot of faces and has begun to learn the names of up and coming gladiators. If you are such a fighter, perhaps she might know of you.
Novel (especially romance novel) enthusiast: Tanvi is in love with love, a hopeless romantic to her core. If you write romance novels (or write anything at all) there's a high likelihood that she will know of you and/or your work.
Inquisitive: She is always interested in learning something new. If she hears that you're an expert in your field, she'll likely want to know more
Thavnairian: Tanvi was born in the fishing village of Yedlihmad. Perhaps you're a figure from her childhood, friend or otherwise.
