The new dungeons are: Underground Katalam, a labyrinth where owning the fortresses will make travel easier; Lunadium, home of the broken-hearted witch Grendal; and Katalamize, a 12-Daeva instance boasting the strongest boss of all of 4.0. On top of those, the expansion is also bringing yet another new type of siege, just like 3.0 introduced a new one with the Hearts in Tiamaranta. The new fortresses will also have two unique additions to the standard fortress instance: a solo instance and a special version for the controlling legion that offers better rewards than the original.
