Gateway Engine

Each planet has a Gateway Engine located in the center of the planet. Once activated, like the Gateway Chambers, it has an Odd Stone to allow for teleportation between the Gateways.

Planets
Each Gateway Engine requires a specific resource to create a Geometric Triptych, which is required to activate the Engine. The Geometric Triptych is unique to each planet and can be created repeatedly.
