Plagueborn Quest
From EZ Server Wiki
Given out by Elgeon Silvershaper, the Plagueborn quest is one half of the Epic 10 quest, and the most brutal. You must kill 750 Plagueborn to complete this half of the quest. Plagueborn spawn by killing anything in Sunderock Springs or Blackburrow. This quest will take a very long time to complete, and it's not shared between the raid if a character dies during the fight and isn't in the zone upon the Plagueborn death. Typically the quest will be complete or near complete around the same time all 3 factions (Orc, Gnoll and Sarnak) are at Ally status.
