Sfena

Sfena was a powerful tiefling and the founder and leader of the Iron Throne.

History
Sfena was once an assassin in Baator, working for her devilish parent. However, in 1347 DR, during a mission on Faerûn, a strange incident occurred: her body transformed into a hard crystalline substance, which had the effect of removing her connection to Baator, allowing her to stay in the Material Plane. Sfena decided to create the Iron Throne as method for cure herself: her plan was to construct a powerful organization and trade it to a powerful devil in exchange for a cure.

The first part of Sfena's plan worked very well and soon thank to her plots the Iron Throne gained a position of prominence. However, the traitorous Iron Throne lieutenant Maready informed Sfena's devil father of her location and in 1371 Sfena was forcibly brought back to Baator.
