Shooting Missiles at the Darkness.
Consisting of a group of shamans from various tribes and their fanatical followers, the Murkei were banished from the lands of the Telsii a millennium ago for discovering and practicing a form of ancient and terrible demon magic. Their refusal to cease indulging in these dark endevours acted as a catalyst for the unification of the various tribes and the creation of the Telsii as one people. Together the tribes of the Telsii purged the evil from their homeland and exiled the Murkei on great ships, sending them forth into the Blood Mists, forbidden to ever return.
The Murkei have not been officially seen since, though villagers on the coasts whisper of great black ships glimpsed drifting silently along deep within the mists, their hulls oozing blood.
