Garukresh is a legendary serpent from Kyonin mythology whose body now forms the serpentine mound known as Erithiel's Hall. According to myth, in unspeakably ancient times. Garukresh faced off against a fey hero from the First World named Erithiel. Their battle was so violent that is supposedly left seas and deserts in its wake. Garukresh was eventually slain where his body now lies at Erithiel's Hall, and the victorious fey hero is said to have built a fantastic barrow palace within the fallen Garukresh's body.
