Sturmbeorn

In the far north of Vilderan dwell the Beornen: a race of bear-men who have developed a primitive culture built around exploration and trade - and, from time to time, plunder. These raiders, or "Sturmbeornen," cross the northern channel and ravage the coastline settlements, pillaging and slaughtering in their quest for power, glory, and battle.

Most of these raiding parties consist of a few dozen bear-men, but a veritable army of Sturmbeornen has recently arrived in the Estherian Steppes - far outside their usual range. Led by the fearsome warlord, General Grell, the Sturmbeornen push ever nearer the Enclave, the last city of the Estherians, and not even the might of the Vanquisher Corps can stop them.
