Muylari was the overseer of the ill-fated mining operation in Silver Valley. He was using amnesia sorcery to make the village of Velaskar forget they were a tourist town, no longer having any memory of the valley or its horses. The tour guide Jaron Galarn regained his memories and tried to free the enslaved horses, who were being used to haul the mining carts. Muylari ordered his men to bury Jaron Galarn alive, but then the ground cracked and released a great evil "wyrm" entity of darkness. Muylari survived while his mining crew mostly or entirely perished. Muylari may have been cursed with immortality.
Muylari was an NPC who appeared around Kelfour's Landing at some point in 1995. He sounded sad and was supposedly seeking his life's end. This is poorly recorded now, and only exists in paraphrases with unknown degrees of embellishment. His master is said to have been a dark rider who saved him and his new wife from giants. The identity of this master is not clear with the available information.
Behind the Scenes
"Muylari" is probably supposed to mean something in Iruaric or less likely Erlini, given its stark similarity to the word Iylari which are the High Elves. Research:Shadow Valley analyzes the story and Shadow Valley itself for its possible deeper meanings. The reason the Secluded Valley is found near The Graveyard may have had more explanation in story events around its release but it is not recorded now.
