Draeden

In the Dungeons & Dragons game, draedens are massive, ancient beings that predate the multiverse.

A draeden's true form resembles a cluster of 20 tubular strands arranged symmetrically around a central node, although they usually appear to mortals as the most deadly thing imaginable.

The 92nd layer of the Abyss, known as Ulgurshek, is actually a draeden who lied dormant while the Abyss formed around it.
