The Whisperer in Darkness
Floating Tentacle Creatures
Large hovering masses of tentacles from the void that use devastating, ranged psychic attacks to attack their adversaries.
Beware when these foul entities work in groups, for they have the unnatural ability to meld with their dead in order to rejuvenate themselves. An exploitable weakness of the tentacle creature is its physical ineptitude – their tentacles are not strong, so you may find safety if you barricade yourself inside shelter.
What these creatures lack in fortitude they make up for in cunning. In windless weather they can ascend to a height of forty feet or more, and will exploit open windows and other high entrances. Additionally, they become even more deadly when they work co-operatively with other underworld monsters. It is clear that they are possessed of either intelligence or instinct, as they defend the Finis through which they enter this world with their lives.
