Gelugon

Rhys's picture

Creatures dedicated to icy perfection, the gelugons are among the eldest and most powerful Baatezu, second only the pit+fiends. Gelugons make up the vast majority of the population of Cania, the eighth layer of Baator.

After serving without any errors for 1001 years, a gelugon is eligible for transformation to pit fiend status. To do this, they must remain in the Pit of Flame for 1001 days.
