A darkmantle is a disgusting, octopus-like creature that clings to ceilings and surrounds itself with magical darkness.1 Three lay in wait with a cloaker in a hall of the sealed Underforge Vaults beneath Argentum, and the party killed them on the Vigil of Remembrance, 1714 PSF.2
Appearance
Darkmantles writhe on the ceilings where they cling.2 They fly.2
Behavior
Darkmantles fill the space around them with magical darkness that no light can illuminate. Those inside it cannot see anything else in it.2 In the vaults, their darkness filled the top of a hall thirty feet high, down to fifteen feet above the floor, and hid the cloaker within it.2 The one Temerity smashed to the floor stopped giving off darkness.2
In the vaults they attacked by dropping onto the party from above and wrapping themselves round a victim’s head, blinding and suffocating them.2 One that dropped on Hazel, in the shape of a dire wolf, could not get its grip because her head was too big.2
History
Session 12
The three darkmantles stared at the party from the ceiling as they entered the hall.2 Temerity smashed one to the floor, where Iva finished it. Another wrapped itself round Iva’s head until Temerity knocked it off and killed it, and Hazel killed the last and hurled it against a wall.2
Session 13
Their darkness had hidden the Vault 20 mural on the hall’s ceiling.3 Hazel took an ink sac from each of the three, a bladder of dark fluid that seems to darken the air around it.3
