Weylan

Weylan was the only child of Baylen, and the great-grandchild to Theandir VI, one of the Kings-In-Exile. Due to a plot hatched by his father to have their side of the family inherit the rights to leading the Greatbeards, which involed the murder of Üdul, the current King-In-Exile, there was a lot of controversy in regards to whether or not Weylan should be allowed to inherit the title. Howere, it was soon discovered that Üdul was to have a child, Urist, who would continue the lineage of Duor Greatbeard.

Weylan never had any children, instead trying to 'create' one synthetically. It's said that Weylan turned quite mad in his old age, trying to fight off his one greatest enemy- Death. Whether or not he accomplished this is uncertain, as one day the dwarf simply disappeared, never to be seen again.
