Waterdeep

A woman in her early forties, with a pale, drawn face and black eyes resembling voids. She had two infernal rubies implanted in her body: one on her forehead and another on her right hand, granting her enhanced infernal powers but contributing to her descent into madness.

Inkeri was ambitious and deeply entrenched in her family's dark legacy. Her pursuit of power through infernal means led to her mental instability. Despite her descent into madness, she maintained a commanding presence and was a formidable figure within House Margaster.

As the leader of House Margaster in the late 15th century DR, Inkeri was deeply involved in dark dealings. She collaborated with her brother, Brevindon Margaster, and cousin, Alvilda Margaster, in experimenting with infernal rubies and demonic phylacteries. These experiments, intended to grant power, ultimately led to her mental deterioration. Inkeri allied with the drow of House Hunzrin, managing a business involving demonic phylacteries. Her involvement with Dagult Neverember, the Open Lord of Waterdeep, included the embezzlement of millions from Waterdeep's reserve. Her downfall culminated in a confrontation with Alvilda, where both women transformed into demons. Inkeri, housing the demonic phylactery of a bar-lgura follower of Demogorgon, was ultimately beheaded by Alvilda, who had become a bar-lgura herself.
