Leagers is an giant octahedron that was discovered in 1960 by a group of 29 Daves which got sucked into a wormhole. Not much is known about it, but the Daves found out you get sucked into it's core if you enter a wormhole with a nonexistent destination. Leagers is constantly expanding in order to not collapse into The Omni Home. The part that isn't in the core is even more unstable than the non-Main Branch Endless Perch, as it ejects about 2/0 Omni Homes per xoctosecond. The temperature is about 32 fahrenheit or 0 celsius here.
The core of Leagers contains about 50 Omni Homes but, until people were teleported there, 85% of it is was just a void with a bunch of Geodeverses here and there. You can get sucked into the core if you enter a wormhole with a deleted destination, primarly because it's litteraly nothing.
Hence, the Core is home to about 95 million entities have got teleported to the Core, including those 29 Daves. The 95 million people live inside 3,628,800 apartment buildings which were built by 40 construction workers who also got teleported to the Core.
The Core is also notably stable, ejecting roughly a Tetraverse per hour.
Leagers has since then been confirmed to be one of the gems of The Gem of Understanding.
