Sailing into the harbour
Not far into questing I entered the Utgarde Catacombs. A quest in there had me run through a heap of ghouls to recover an artifact while surrounded by a protective shield. The shield burned their faces. XD
Sizzling ghoul flesh
Next, it was underwater for some collecting. I was even given a diving helmet so I could breathe.
I met up with the Lich King during my next quest circuit.
