Hunting Skywhale has become a caveat of Norheim culture. While many see the act as barbaric the people of the spires consider the beasts sacred and harvest and use every single part of the creatures the hunt.

Rumors have come in with merchant ships about a never-ending slum to the east and the massive sky-beasts that clean the thick air.
