While quests in Icecrown can often be picked up independently of each other, a set of breadcrumb quests lead the player from one quest hub to the next: * Argent Vanguard * Valley of Echoes * Crusaders' Pinnacle * Skybreaker (alliance) or Ogrim's Hammer (Horde) * Ymirheim (King of the Mountain) * Shadow Vault * Black Watch, Jotunheim, Death's Rise, Icecrown Citadel (opened up in roughly that order) * After Icecrown Citadel: * First Legion Forward Camp * Sindragosa's Fall
