You ate Finnish souls? Assuming those were real Finns, not brainwashed captives whose souls were suffused with a soul-poison, eating a Finnish soul is a certitude for death.
They're actually kinda like puffer fish. They're not deadly if you prepare them correctly. I mean if I never ate Finnish souls, there'd be a lot of immortal Finns out there, and we just can't have that.
