That Which Sleeps Beneath
Also known as the Sleeping God and the Open Eye. This is is the deity (or entity) that was awoken in the earth deep beneath Thalbos during the Night of the Open Eye. Little is known about TWSB itself, as most who seek it out or encounter it are driven mad. However, some Duergar have learned to harness this madness and use it to prevent others from gaining access to the ruins of Thalbos. The few remaining sane Duergar have vowed to let none enter those ruins, for fear of TWSB gaining even more power, or coming more fully awake.
“May You Remain Unseen” is a frequent ‘blessing’ said by many Duergar. Similarly, referring to something as ‘unseen by’ is the same as calling it ‘miraculous.’
