Olga Ponyatevna

A fighter from Novgorod last seen about 75 years ago. First person known to wield the Black Sword, which greatly enhanced her abilities as a fighter. Became increasingly unstable until she disappeared.

When the Byzantine Envoys finished hacking the Tarot Dungeon and got to the cave with the corrupt pool, they saw an arm holding the Black Sword rising out of the middle of the pool. As Nicolae poured Holy Water around and on the arm, it moved toward the edge of the pool and revealed itself to be a woman, presumably Olga Ponyatevna. She stepped out of the pool before running herself through with the sword and died.
