Bottomless pit

A massive hole located in the very northeastern corner of Jaga Moraine, right next to where Ssissth the Leviathan or Ediehl Shockhunter spawns.

Trivia

 * The hole and the missing Norn is a reference to the Jules Verne novel, A Journey to the Center of the Earth, where Otto (Professor Lidenbrock), Axel and Hans travels to the center of the Earth through a volcano on Iceland.
