Adishana is from Parta, the capital city of the Kingdom of Bharat, far to the east of the Caverns. Growing up, she exhibited much curiosity and proved to be adept at creating small gadgets that served as toys or tools. As her skill developed, she established a thriving business, selling these gadgets, eventually developing a clientele that would commission her for specific gadgets.
One such commission from Ghanvi, King of Bharat, required very rare alchemical materials. After an extensive investigation, Adishana found these materials for sale on a trade caravan from the west. She did not realize that these materials were clever fakes.
When Adishana finished the gadget, she was invited to the royal palace for an audience with the king and an opportunity for her to demonstrate the gadget. The faked alchemical materials had worked in her laboratory, but under the stress of an extended demonstration, they failed and the gadget exploded. The resulting fire burned down a third of the royal palace and burned over half of Adishana's body, including her face.
Adishana's laboratory was seized, and she was exiled from her home kingdom. That was three years ago. She has finally tracked the origins of those fake alchemical materials to the Caverns of Chiesa the Unspeakable, and Adishana wants vengeance.
