Gain the favor of the Lich King
As the undead armies closed in on the Sunwell, a high elf named DarKhan Drathir aided Arthas by lowering the shields surrounding the Sunwell. In betraying the high elves, DarKhan hoped to gain the favor of the Lich King. However, the most immediate result of his Star Wars Galaxies credits treachery was an explosion that knocked him unconscious and scattered most of the Sunwell powers.
