Bodhi is an elven vampire who was expelled from Suldanessellar, which would lead to her becoming undead. At the start of Shadows of Amn, she is in charge of a vampiric thieves' guild designed to overthrow the Shadow Thieves in Athkatla.
Much of Bodhi's backstory prior to Shadows of Amn is left ambiguous. Once an elf living in Suldanesellar, she was a close confidante to Jon Irenicus, a powerful spellcaster who refers to her as a "sister", even though their actual kinship is never verified. She assisted him in his attempt to become a god and suffered the same punishment as him when the plan failed. Both Bodhi and Irenicus were stripped of their connection to the elven race and were cast out of the elven city. It is implied that the nature of the punishment significantly shortened Bodhi's lifespan, as she voluntarily turned into a vampire as means of survival.
In the beginning of Shadows of Amn Bodhi has settled in Athkatla, taken control over a guild of vampires and got involved in Irenicus' new plot to drain the Tree of Life and become immortal.
