Many centuries ago, King Asbjorn Doomclaw ruled the northern lands of Urskaya.
Things in Urskaya were never entirely peaceful, but Asbjorn’s reign was particularly troubled; his kingdom came under attack from the Daemon Lord Kurandara, whose horde of mindless Hellspawn would descend from the southern mountains at night to terrorize the Urska (and believe me it is VERY hard to terrorize an Urska). It did not happen every night, and never in the same place twice. This went on for years.
Every morning, after an invasion happened, Asbjorn would rally the Urskatyrs to go hunting, but Kurandara and his legions could never be found.

Asbjorn gradually grew enraged. He began to sleep during the day and took to travelling the mountains at night, Urskatyrs in tow, looking for signs of the Daemon horde.

Finally, one night when the moon was full, Asbjorn found them, preparing for an invasion, with Kurandara himself standing by his summoning portal, and Hellspawn pouring through. Without thought, Asbjorn charged him. The battle was fierce and raged on for many minutes until King Asbjorn Doomclaw grabbed the Daemon Lord and they fell back through the portal.

Neither was ever seen again, though it is said in Urskaya, particularly in the lands down near the mountains, that on nights when the moon is full, and the veil between worlds is weak, you can still see King Asbjorn Doomclaw roaming the mountains. He is changed and corrupted by chaotic forces, but he still guards the southern reaches of Urskaya against the Daemons.
