Knights of Tezoth

No. Sarnissa was the leader of a mercenary squad. At one point, we started recruiting NPCs. One of them arrived with giga-stats and skills, raving about how great Sarnissa was. Before one quest, he decided to give her a ring as a token of gratitude. This turned out to be a trap; he kidnapped Sarnissa, sawed off her head, and put it in a jar on a shelf, since she was a giga-vampire and the guy loved hunting powerful creatures. The quest fell apart because all the battles relied on her imba skills, and the exp itself came to an end.

Oh yeah, and the best girl wasn't her, but Elrina from RI2.
