Nightgaunts at The Great Abyss

Another Lovecraft inspired work of his creatures, the Nightgaunts.

"Nightgaunts are vaguely humanoid but are thin, black, and faceless. They have slick, rubbery skin, a long, barbed tail, and hands they use to "tickle" their victims into submission. They make no sound.
Nightgaunts guard Ngranek, a perilous mountain on the isle of Oriab in the Dreamlands. Sometimes they capture unwary climbers and tickle them into submission, with their clawed hands and tails, and carry them to the lower reaches of the Dreamlands."
