Tesseract

The Tesseract is a stable energy matrix built to contain the power of the Space Stone, one of the mythic Infinity Stones long thought to be mere legends.

Very few people are privileged with the knowledge that an Infinity Stone is inside the Tesseract. It is mostly known as a source of near-limitless clean energy and a useful tool for creating Boomtubes. Unlike artificially created warp streams, there is no limit to the mass or reach of the Tesseract's portals and no trace neutrino emissions. The scale of what the stone can move is limited only by the willpower and focus of the user. A strong enough mind could potentially relocate an entire planet-- but very few beings in creation are capable of channeling such cosmic energy without being destroyed by it.
