Dagoth Morin was a Sixth House priest, apparently of some renown, who served Dagoth Ur during an unknown time. The details of Morin's life, including what type of Ash Creature he was, are shrouded in mystery. After his death, he was entombed deep beneath the House Dagoth base of Kogoruhn in the Bleeding Heart caverns.

Dagoth Elam was set to guard the Tomb of Dagoth Morin, upon which rested the Shadow Shield an artifact which may have belonged to Morin in life. This shield would later be sought by the Nerevarine, who would fight to Morin's tomb to recover it.
