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. Angusks are giant multi-legged creatures that have somehow evolved the ability to direct the Island of Undoing’s leach of energy to a specific leg, which withers and falls off to be replaced by another. Some believe that there’s no way to angusks could have evolved this mechanism on their own.
2. Cephaleen spiders have, if killed, something that is notoriously hard, or found dead, metres of sticky webbing inside them that can be harvested. It’s rumoured that some are trying to come up with a way of breeding and keeping the spiders in captivity, so that the webbing can be more easily harvested.
3. Delormi is protected by a large fence to stop the island’s creatures from attacking. It’s rumoured that the fence is slowly deteriorating, due to the villagers lacking the resources needed to maintain it at full strength, and that there are worries the wall might either have to be made smaller or risk having it give way under an attack.
4. Most plants on the Island of Undoing that the form of multicoloured moulds. There are rumours that being exposed for too long to any specific type of mould is unhealthy for the one doing so, and that in some cases they may be devoured by the mould’s spores and turned into fertiliser for the next generation.
5. The Carrils are a Carriles cult of worshippers outside Delormi who believe that the island is a god and they are seeking a way inside the village’s wall to destroy the Tower of Life. It’s rumoured that the leader, Tiass, is seeking out any newcomers to the island to see if they have anything that would breach the wall.
6. The Island of Undoing drains the health from living creatures on it, but there’s a rumour that this only applies to creatures that are on or near the surface. Some believe that if you were to dig down deep enough, you would be protected from the island’s effects.
7. The Tower of Life in Delormi on the Island of Undoing is a machine that thumps the ground at night, protecting those within the affected area from the island’s draining of life. Some want to examine the machine to see if its effects can be duplicated, but most are opposed to tampering with it out of fear that doing so could break it entirely.
8. Those bitten by cephaleen spiders whose bites turn into the symbols found on their stomachs can open the doors to beneath that also bear the same symbols. This has led to rumours that the spiders are some kind of mechanism for opening the doors that has malfunctioned over the aeons.
9. Tiass, the current leader of the Carils, found the majority of the group from the survivors of a shipwreck. Though up until now those survivors have been eager to follow Tiass’s god rather than their own, it’s rumoured that some of the former crew are becoming increasingly uncertain about this.
10. Zunak are abhumans who live on the Island of Undoing. It’s said that zunak cannot be found anywhere else, leading to rumours that the abhumans are created by the Island from some of those who die from the island draining all their health, who are then reborn, or reanimated, as creatures who are now immune to the effects.
