Calis Wraithson was the leader of a green Undead Scourge base located near Hearthglen. One night he and Venim Iceblade decided to attack Hearthglen and all the nearby villages. They sent an Undead Caravan to the villages and undeads against Hearthglen.
Meanwhile in Hearthglen Arthas arrived and killed the infected villagers, and then prepared the defense of the city. After a long and unsuccesfull siege Calis Wraithson decided to attack by himself, but at he and his troops were destroying the city Uther the Lightbringer and his Knights of the Silver Hand arrived and defeated the undead.
Calis, however, managed to survive and retired to Northrend. The next month Arthas arrived Northrend to hunt down Malganis and found Calis in a green undead base. Calis tried to kill Arthas and all his warriors, but they were reinforced by Muradin Bronzebeard and some dwarves, and sent a counter attack, killing Calis in the battle.
