Skoggothur

An amorphous, blob-like creature of tremendous power that dwells under the seas and oceans of Midhgardhur. The skoggothar were bred as a slave-race by beings from beyond the skies, from another world beyond the Void between the stars. Some creatures still know the techniques of enforcing obedience from these terrible creatures, making some of them servitors and slaves, but many others are wild, beyond the control of any other sentient beings.

Source: These creatures appear in the stories of H.P. Lovecraft as shoggoths. "Skoggothur" is an attempt to render this name, coined by Lovecraft, in Norse phonetics and nominal declensional ending. They are first mentioned in Midhgardhur in the story "Sons of Aegir, Daughters of Ran"
