Useless Tuba Banshees

The Useless Tuba Banshees are spirits of Poorthwart that appear in very rare situations, to inform those who have just had a confusing conversation that they are not losing their minds; that, in fact, the conversation was every bit as confusing as they thought. They travel through a system of transports known as night cubes, about which little is known.

It is unknown if they are related to the Banshees.

They appear to Tyco Brahe and the Admiral in Poorthwart: The Cataclysm.
