The Kingdom of Light
The mightiest demon to terrorize the Dark Age, Hobnarannon is a name universally feared and reviled by most civilized folk.
Even now in the Kingdom of Light, his full name is never spoken aloud, for fear that it will summon the demon himself. However, his name in short form is often used as a bogeyman to frighten small children. “Eat your greens or old Hob will get you,” is a common way of pacifying unruly children.
