Kaethe Nyx
Kaethe has lived many lifetimes. Turned by her twin brother Kael during the Russian Revolution, they traveled the world exacting revenge on those who massacred their family. Vengeance satisfied, they've gone their separate ways, meeting only rarely in the intervening centuries.
Married thrice, she is now alone. She carries titles of a bygone era, though she rarely uses them or speaks of them.
Kaethe is an expert in poisons, thanks to the twins' years as assassins. She has turned her skills to Healing, finding that she has a gift for such. She is a Seer as well, though that gift is transitory and unreliable, as such talents often are. She now travels the globe, searching for some elusive fulfillment that is lacking in her existence, something she's not really aware is missing at all.
