The Gates of Muspell are a special area which originally featured in Campaign before making its return at Conquest Mode.
The Gates are either already appeared or summoned by Hvedrung, the allegedly mortal disguise of fire giant Surt. However, he needs Gjallhorn to summon Eldthur horde to destroy Bifröst and enact the Ragnarok. It's up to Rig and co. to disable the gate and stop his army's advance.
In Conquest Mode, the Gates appears as obstacles in Mispell's Wrath. As before, they spawned Eldthurs horde to either attack the player's clan or Bifröst itself.
- Appearance-wise, they resemble Gates of Helheim.
