Katla of Birka
Katla, the beautiful and once-powerful Jarl of the region around Sigtuna
Tall, beautiful and ambitious.
Katla was a powerful Swedish Thane under Jarl Vitharr, but she deposed him and replaced him with the help of her full-blooded alfar husband Orn Alfar. She ruled in Sigtuna only briefly, however, as she was recently driven out by the new King Erik Segersall. She still has influence in Birka (Birch Island, south of Sigtuna) and Stockholm (inland), while Erik controls Sigtuna and Uppsala. The two are currently engaged in a fight for power in central Sweden.
In Birka she has a local foe, a relatively popular missionary from Germania named Ansgar, preaching the religion of the White Christ. Ansgar is pretty open about his belief that Orn is a demon.
