The moredhel are those elves who once served the Valheru. When these were defeated by the gods they struggled to survive in the world; Ashen-Shugar freed them from their slavery but being long influenced by their masters' aggression, the moredhel sought to regain the former grandeur of their masters. They decided to collecting relics and weapons of the Dragon Lords and continue their heritage, the Dark Path. Their quest for power led to the near genocide of the Glamredhel race.
The other Elves who knew their scheme also sought the relics of the Dragon Lords and destroyed them so that they wouldn't fall into their hands, but some of them could not be found.
In Triagia, Moredhel would often ally with the goblins whom they would send against humans. They lived mainly in the Green Heart. Once they attacked Carse but were repelled by dwarves. About 10 years before the Riftwar, they stirred up the goblins against Crydee.
After their defeat at Sethanon, the Moredhel yearned, driven by a belief the Kingdom had tricked them and imprisoned their leader, Murmandamus. Battles raged between rival clans who sought to control the future of the Moredhel. Those who had migrated from the Green Heart during the Riftwar chafed to return to their ancient forests, but were captured or killed as various chieftains attempted to brutalize the clans into a fearful union.
When at last a Moredhel chieftain named Delekhan seized control of the ancient fortress Sar-Sargoth, he vowed revenge for the wrongs done to the Moredhel as he unfurled the battle standard of Murmandamus.
Physically, moredhel are indistinguishable from other elven races. What set them apart is their lust for violence and power. On occasion, a moredhel may find themselves changed, turning themselves away from the dark path. They would travel to Elvandar, home of their Eledhel kin, where they would be welcomed back into the fold, becoming indistinguishable from their kin. These pariahs were rare, since their Moredhel kin would sooner slay them than to allow them to travel to Elvandar.
