After Ragnar's soul has been captured by Nyarlathotep, the god of the dark arts, and death, players must travel to Helandiht because Reinwald, father of Elijah, have been assassinated (murdered by Nyarlathotep).
Actually, it's Sigurd who acknowledged in a pact with Nyarlathotep for power in the Reich.

It is said that the murder committed by a cult of dwarves who worship the rotting body of a dark magician. The cult is said to live in the fort of Dogh Boldir, a fort dug into the rock Surtr.

The body turns out to actually be Nilfgur Copper Skjöld, the ancestors of Ragnar Copper Skjöld (Max)
When the dwarfs in the fort discover that someone carries Angurvadal they will immediately try to reason with him, or flee in panic from him. They will ignore their posts and flee deep into the caves.

A couple of feuds with the weaker ones who do not manage to escape later, they will possibly be led to the tomb of Nilfgur. It is dusty, then get dwarfs has dared touch it because of superstition.

Written on the grave behind a thick layer of dust is "Nilfgur." When you dust the rest will name "Copper Skjöld" show.
Now Dvärgakungen prove to the players, and prepare for battle. Players should by now resonating with the dwarves, and try to tell me that Ragnar Copper Skjöld is a comrade of theirs.

After the players have explained the situation to the king, his army to obey to the smallest detail. Players get full access to the fort Eternal Guard (Dogh Boldir)

The King will explain why they adore Nilfgur, and how they want to defeat Nyarlathotep.

After this, the Troll King to lead the players to Veisír Kostlakót, historians and mystery connoisseurs of the fort. He has for some time recognized that the only way to defeat Nyarlathotep is that a person with a pure soul defeats by Astral hammer. Dwarves souls are condemned as unclean, as they're made out of stone. The only "pure" from the perspective of the soul is the people and the elves, when they come directly from the inner gods.

The idea is that Elijah Silver (William) should take up the hammer and defeat Nyarlathotep. In the last final battle will Ragnar  and Reinwalds soul returned to their corpses. This is expected to take place by the players to get to the external reality, seek Nyarlath-oteps temple and battle against his three forms.
