Numenera is a game published by Monte Cook Games. Its setting is the Ninth World, and this list has ten rumours for that setting. The rumours, which are similar to the Hearsay that can be found in the official books, can be used as adventure hooks or as simple misinformation.

1. A tower of living, greenish flesh, known as the Twisted Spire, stands near the centre of the Amorphous Fields. About three quarters of the way up is a ring of metal called the Halo, that slowly spins around the spire. There are rumours that the speed at which the Halo is turning has been gradually increasing over the years, and that it is now increasing in speed at a greater rate.
2. Dalthius is a well-known figure in Vebar, the City of Night in the Amorphous Fields. They were found in a metal cylinder not far from the city and seems to have difficulty in open air and sunlight. Dalthius is known to be friendly and helpful, as well as widely liked and the first to leap to the city’s defence. There are occasional murmurings, though, that Dalthius’s friendly nature hides a much darker secret, and that they are nowhere near as pleasant as they appear.
3. Fungi are the only things that grow in the Amorphous Fields, of types not found elsewhere, and whilst some are poisonous, others have valuable medicinal effects. It’s rumoured that some of the fungi are predatory as well, putting to sleep living creatures with spores, then feeding off their corpses.
4. Only a few people live in the unstable terrain of the Amorphous Fields and most outsiders consider them insane. The inhabitants know the routes across the terrain that are, mostly, safe, and live in areas of continuously stable ground. However, it’s rumoured that a few of these supposedly stable settlements have been swallowed up by the churning terrain, suggesting that the ground the settlements are built on is not as stable as might be believed.
5. The inhabitants of Vebar, the City of Night, an underground city in the Amorphous Fields, worship a being called Ourthalas that is said to live in the Cave of Life-Giving Shadow. It’s rumoured that this cave does exist and it’s close to Vebar, and that Ourthalas’s blind wife-priestesses know how to get there and take sacrifices of intelligent beings to feed to their god.
6. The ligoshi of the Amorphous Fields are house-sized bioluminescent jellyfish that swim in the liquid below the ground, emerging now and then when the crust breaks and floating in the air for hours. The ligoshi seem to enjoy wrapping their paralyzing tentacles around creatures, and some speculate the jellyfish may be more intelligent than they seem, doing this out of a love of cruelty.
