Sparshöng

Spar-Shöng is the God of Just Violence.

Background
At Paytousheh he attended a meeting of the gods after Lanfeust won his trial before the gods. The human address the issue of Lylth the Eternal, a monster from another world. While the gods could not ethically use their powers to commit mass genocide, even if to save the world, Spar-Shong gave the hero a magic seashell that would summon all the Banshee-Lylths on Troy to a single location. Once the shell was broken an impenetrable bubble would envelop them, trapping the user and the swarm until one or the other dies.
