Skorgrim was a male Dourhand dwarf King from ancient times. He led the Dourhands clan to attack the Refuge of Edhelion, an elvish settlement, seeking for the power of immortality within the relics the elves kept. He managed to destroy most of it but was stopped when an elf named Talagan brought the library's walls down upon them both, killing them and ending the conflict. Sometime before the War of the Ring he was revived by members of his clan and he started leading them once again.
