Ysirgeis is the one who rules over cold, death, and fear. Those who wish for safe passing of a loved one, invoking fear in others, or the power of ice pray to them. Anyone who wishes to speak or see beyond the veil need their blessing before doing so.

Cultivate fear and awe.
Provide comfort and guidance to those in their final moments.
Interfere with natural death.
Ysirgeis started seeing the veins, the veins of death. They ended up digging themselves into the Frostveil Rift, connecting with its foreign magic, and becoming one with the land. Their ability to see death and mastery over ice earned them a spot in the The Primary Divinity. Their presence started inspiring fear in mortals, and they were encouraged to take this domain as well.
