Dead Scar The Dead Scar is a path of Blight that runs through the Kingdom of Quel ' Thalas . During the Third War , the armies of the Undead Scourge — led by the death knight Arthas Menethil , Crown Prince of Lordaeron — marched up this path from Lordaeron all the way to the Sunwell Plateau , killing everyone and destroying everything in its path . The Dead Scar practically splits Quel ' Thalas in half , all the way through Silvermoon itself . Today , the Dead Scar remains in the rebuilt Quel ' Thalas , as a reminder to all who live there of the horrors committed by the Scourge — and as an incentive to seek their destiny beyond the Dark Portal . . . Origins . After returning to Lordaeron and murdering his father , King Terenas , Prince Arthas was instructed by the dreadlord Tichondrius to bring the corpse of the necromancer Kel ' Thuzad ( whom Arthas had killed not long before ) to the Sunwell , the source of the high elves ' magic . After obtaining a means to transport Kel ' Thuzad ' s remains — the urn of King Terenas , guarded by Uther the Lightbringer and the surviving paladins — Arthas and the Scourge began their march across the Plaguelands of Lordaeron to the gates of Quel ' Thalas . Smashing through the Elfgates that defended Silvermoon from invaders , Arthas ' forces destroyed all in their path , killing everyone they saw , and blighting the very land they trod upon . The path they took across Quel ' Thalas remains burned into the soil today , from the entrance to Quel ' Thalas ( north of what is now the Eastern Plaguelands ) all the way through Silvermoon , splitting the elven capital in half , before ending at the doorstep of the Sunwell itself . By the end of the campaign , Kel ' Thuzad had been resurrected , and the Sunwell defiled — thus cutting the elves off from their source of magic . Today . As the blood elves begin to rebuild their homeland , the Dead Scar remains a blight on the otherwise intact lands of Quel ' Thalas . It begins at Deatholme , the Scourge headquarters in Quel ' Thalas , and runs through the Ghostlands and across the Elrendar River into Eversong Woods . The path then continues across Eversong Woods and through the shattered main gates of Silvermoon . The path abruptly stops on the coast of the North Sea , but picks up once more on the southern tip of the Isle of Quel ' Danas , the location of the Sunwell . There , about midway through the island , the path ends , overlooked by eredar warlocks , wrathguards , and pit lords in the service of Kil ' jaeden , battling the remnants of Arthas ' forces all up the path . At the northern end is the pit lord Brutallus , who commands the battle against the Scourge remnants , all the while verbally sparring with the blue dragon Madrigosa . At the East Sanctum of Eversong Woods , located along the edge of the Dead Scar , Apprentice Mirveda conducts tests of the soil and has come to the conclusion that the damage done to the land of the Dead Scar is irreversible — another reason to leave Quel ' Thalas and seek the destiny promised in Outland . The undead presence along the Dead Scar is still considerable , even near Silvermoon ; though they are fairly weak , their numbers are enough to keep the Silvermoon Ranger Corps busy , fending off the undead marauders . As one travels down the Dead Scar into the Ghostlands , the undead minions become stronger . The strongest undead legion in Quel ' Thalas is behind the walls of Deatholme , the Dead Scar ' s southern terminus — where the traitor Dar ' Khan Drathir and his lieutenants command the Scourge efforts in Quel ' Thalas .
