Kongregate

Kongregate acts as a doorway to many different worlds, and is the cross-roads for many universes in the Digidechtrine. It can be accessed only by portals to it, which take the form of massive crystals of kangorinite poking out of the ground. If you were to touch it, you would be transported to Kongregate next to the portal back to your home universe. The landscape of congregate is that of bare stone, the stone being kangorinite oxide compressed into sedimentary rock. Three-meter high perfect crystals of kangorinite dot the landscape at regular intervals, each one a portal to a different universe, visions of what's happening in that universe appearing on each side of the crystal. It is inhabited by man-sized ants carved from obsidian who roam the landscape scanning the travelers' minds for sinister intentions and if they detect any, they are teleported under the earth by the ants. Below the surface and kangorinite oxide regolith, the kangorinite oxide becomes more and more smooth, then fading into solid silverite. Carved into the silverite are cubic rooms of varying size. When a person is teleported down, ancient and mystical minerals breathed in from the air suspend the cycle of aging, and floating blades forever torment them until their certain death, upon which their minds are transformed into an obsidian ant. Here is a link to Kongregate if you wish to interact with the denizens of its connected worlds. Kongregate is the only place where Kangorinite occures naturally. This universe was contained in the Digitechtrine, before it was destroyed in the Last Great Purge.
