Ghroth
From Multiversal Omnipedia
Ghroth is an Outer God, known to some as the Harbinger. Ghroth appears as a dark object the size of a planet with a central red eye (it keeps it closed when it wants to travel inconspicuously). It is prophecied to reawaken the Great Old Ones when the stars are right. Ghroth has visited Earth and other worlds (such as Shaggai), bringing about mass extinctions and total destruction.
