Synopsis
The heroes activate and travel through the Skittergate below Helmgart to the Rotblood encampment in Norsca. From there on they must find a way to destroy the Skittergate for good.

Event
On their arrival in Norsca, the heroes travel past the gate's mechanism, which requires a keystaff to re-activate. Fighting their way through icy caverns, slippery cliffsides and a part of the Rotblood camp itself, they come across Gatekeeper Naglfahr, who guards the keystaff. This foe must be dealt with swiftly before the blessings of the Dark Gods eventually turn him into a Chaos Spawn, with much deadlier potential. Having retrieved the keystaff from this enemy, the heroes manage to destroy the Skittergate's warp-generators, leaving them a few moments to escape from Norsca's clutches, back into the sunken heart of Helmgart.

Finale
Upon returning to Helmgart through the Skittergate, the heroes find themselves at the mercy of Rasknitt himself. He climbs atop his Stormfiend mount known as Deathrattler, wielding dual Ratling guns which will target heroes at random with a hail of warpstorm bullets. It is possible to knock Rasknitt off his mount for a brief moment to deal damage, but he is only able to be slain after Deathrattler has been dealt with completely. When his mount is defeated, Rasnkitt will continue fighting by utilising warp magic, both to teleport from corner to corner of the arena, and to damage the heroes relentlessly. Once defeated, Rasnkitt will fall to his knees before ascending in a storm of warp energy, finally blowing him to pieces as the heroes make their escape through the crumbling under-city.
