Svartalfheim & Nidavellir - 4th part

The Hall of Durin - Those it sound familiar? Tolkien did not choose this name for a very important Dwarf, from whom the great dwarvish kingdoms came, for no reason.
In the Norse mythology, Durin is one of the oldest fathers of the Duergar (dwarves). Many were the deeds of this great dwarf along with his friend Dvalin. Durin was chosen as the first chieftain of the Duergar, and his memory is still loved and revered. His hall is one of the grandest cavern-mazes in Nidavellir, but rather than keeping it as a private hall or passing it along to the next chieftain, his relatives decided instead to open it to the public as a place of respite and peace. His hall is one of the few places were one might find peace of mind and spirit in Nidavellir.

As I have already mentioned it, Durin had a powerful companion, Dvalin, one of the most powerful Duergar there is. His father was the famous Mimir and his mother Lovar. Both had four children, Dvalin, Alfrik, Berling and Grer. These are the brothers who made the famous necklace Brisingamen, the same that Freyja wears.
It is said that he (Dvalin) is one of the four deers that guard Yggdrasil and the way to the spirit world, shapeshifted along with the other three, a Jotun, and Alf and a Man.

One of the few surface areas of Svartalfheim where Duergar can be found, is in Joruvellir, in a particular area called Aurvangar, where a great grave mound was built and where Lovar and her Duergar lover, Svarin, rest in peace. This place also has underground areas of course, but it is unique because of the grave mound that towers above the flat plain. This place isn't hard to find, for it lies near the only wetlands in Svartalfheim.

The mountains in Svartalfheim hide many secrets, one of those is Byrgir, an empty well standing on a mountaintop. It is said that from this well at one time it poured forth magical waters that gave the gift of poetic power and ecstasy, but Ivaldi magically emptied it, which stopped its flow and ensured that it was in limited supply, and thus more valuable. Ivaldi's brothers, Fjalar and Galar, came to him with Kvasir's blood, Ivaldi lent them enough water to mix the blood and thus creating the Mead of Poetry, intending on a share of it. However,they fled with the Mead of Poetry and Ivaldi's cursed them, that they would not live another six turns of the Moon. It would  be true, as Sutting hunted them down and killed them soon after for the murder of his parents.
