The area known as the Ruins of Silvermoon makes up the western half of Silvermoon City, the capital city of the blood elves and the former kingdom of Quel'Thalas. It is split from the reconstructed eastern districts of Silvermoon City (now the capital of the Horde's blood elves) by the Dead Scar, the path taken by Arthas Menethil and the Undead Scourge on their way to the Sunwell to resurrect the dead necromancer Kel'Thuzad. As they marched across Quel'Thalas at the bidding of the dreadlord Tichondrius, Arthas and his warriors corrupted everything in their path. The Scourge smashed through the Elfgates defending Silvermoon from attackers and decimated the Thalassian Ranger Corps, led by Sylvanas Windrunner, before finally reaching the Sunwell Plateau and placing Kel'Thuzad's rotting corpse
