Murmandamus was a moredhel warlord who united the moredhel clans of the north in a Great Uprising to conquer the glamredhel before the Riftwar. He died in the battle of Armengar.

Since his death, legend and myth have turned him into a messianic figure with deep meaning for all the moredhel, as the only one to ever successfully unite the moredhel.

This superstition was exploited after the Riftwar, when a Pantathian took his form to bring back the Valheru.
