Fyrsnaca

The Fyrsnaca is a wyrm native to the cold north, often found in the vicinity of hot springs and volcanoes, which it uses to reproduce. When it enters its reproductive cycle, every 100 years, it dives deep into the heat to lay a sac of eggs. It then stays with the eggs for 25 years until they hatch into the immature state of the Fyrsnaca, a clutch of red worms. During this period, the Fyrsnaca cannot survive outside of the heated water or lava, and it is quite irritable as it cannot hunt. Otherwise it is a fearsome predator, eating polar bear, seal, and whatever else it can get its teeth around. The Nords view the killing of a Fyrsnaca alone to be an exceptional deed, and often if there is a kingship crisis, at least one of the contenders will go Fyrsnaca hunting.
