Hey guys! I was just wondering now when the lich king is defeated and all, is the death knight starting zone still the same? Is the lich king still on that ship and giving again the same quests and stuff? I am really curious how it works now so hope someone answers. Thanks!!

Yeah he is. Those were unchanged because on the WoW timeline that happened before the cataclysm (no more death knights being made after Arthas is dead, obviously). And the "ship" is Acherus, the Ebon Hold, a floating Necropolis like Naxxramas. All the quests are the same.

Yep, that starter area is still the same.
