Arc 9The Fall of Quel'Thalas
Karin warned Quel'Thalas of the Horde and Amani Troll invasion, then helped the elves and Alliance drive the attackers back, though dragonfire and the destruction of Kul Tiras’s fleet brought heavy losses. After the Horde withdrew for winter, Liadrin left to seek paladin baptism, Sylvanas settled her old dispute with Karin, and Kel'Thuzad called for a return to Dalaran to plan against the Horde.
- Orgrim Doomhammer and Zul'jin led the Horde and Amani Trolls toward Quel'Thalas, while Karin warned Sylvanas and then the Silvermoon Council of the coming invasion.
- After Karin convinced King Anasterian to prepare, the Horde overran elven outposts, and Karin helped evacuate villagers before joining the defense.
- Gul'dan broke through the elves’ defenses, but Anasterian and the Grand Archmage wounded him, and Alliance reinforcements forced Orgrim to retreat.
- The elves and Alliance pursued the Horde, and Anasterian declared that Quel'Thalas would join the Alliance.
- Orgrim sent dragons to burn the forest and attack the pursuing fleet, and Derek Proudmoore died after Karin carried him from the wreckage.
- After the Horde withdrew for winter, Karin gave Liadrin Glamdring before she left to seek paladin baptism, and Sylvanas settled her old dispute with him.
- Kel'Thuzad joined Karin and Khadgar, agreed that Khadgar would avoid punishment through daily meditation, and proposed returning to Dalaran to plan against the Horde.
