Hill Person

Hill People are a Precambrian spaceborne species who were trapped in Earth's core, which transformed them into hill-like beings.

Biology
In their true forms, Hill People are amorphous spaceborne spore-like energy beings, capable of traveling across space. However, they can be caught in gravity wells, such as from forming planets, which can forcefully fuse them to the object generating the gravity well. However, Hill People can manipulate rocks, thus creating bodies for themselves that often resemble rocky hills with scowling humanoid faces, albeit lacking noses. They can reshape their hill-like bodies to semi-humanoid forms, and make rock spires rapidly burst out of the ground. Notably, Hill People can survive having their bodies destroyed, which would just revert them to their energy forms, and they can possess other rocks, even possessing multiple rocks at once. Additionally, Hill People are telepathic, and can control the minds of Humans within a certain range, although pure iron can block their mental abilities. Hill People can live for billions of years, and being spaceborne, they do not need oxygen to survive.

Culture and society
Hill People are generally peaceful, and have rallied together against any hostile member of their species. They have not developed their own technology, although they appear to know how to construct highly advanced technologies, and most are content with wandering the galaxy. Only one member, Spragg, has displayed hostility.

History
Two billion years ago, the Hill People drifted through the Milky Way as inert spore-like energy beings, eventually finding the Sol System, where they got caught in the gravity well of a forming Earth, being trapped within the planet and fusing to its internal material. Over two billion years, they developed mental powers and terrakinesis, creating seismic activity as they moved. Despite surface repercussions of their movement, Hill People remained mostly peaceful, and kept to themselves underground. Sometime in the 20th century, a malevolent Hill Person named Spragg used seismic activity to reach the surface of Earth, surfacing in Transylvania, where he used his mental abilities to mind control a small group of Humans near him, making them bring the population of a nearby village within mind control range. Finding that his abilities were limited to that range, Spragg ordered the Humans to build a device capable of boosting his abilities, referred to as "dynamo," which took the form of a platform under Spragg, which he intended to use to take over the planet.
