Pesa is a location in Ghost of a Tale. It was a city in Muridea before the War of the Green Flame, after which it was annexed into the lands of the Rats of the Red Paw.
All Mice, upon reaching adolescence, must travel there on the Pesa Road to register their name and vocation with the authorities of the region. When the journey is complete, and they return to their homes, they are allowed to don the hood or hat of their profession.
