Gateway Portal

The Gateway Portal, also known as the Unidentified Satellite, is the location of the ending to the adventure across the solar system. It is hovering above the sun, and can only be accessed after activating a Gateway Engine. In order to activate the Gateway Fast Travel Network on the satellite, the player must first travel there by shuttle and interact with the Odd Stone on the outer platform. This allows travel between the satellite and any active Gateway Engine.

Structure
The Gateway Portal has a round platform in the center, which is divided into seven concentric circles, one for each Planet and space for an Odd Stone in the center. Attached to this platform by illuminated ramps, are five outer platforms. Four of them offer landing space for Shuttles, the fifth has an Odd Stone, allowing players to travel to the cores of all seven Planets, after they have been activated.

Activating the Center
Once all Gateway Engines have been activated across all seven planets, the player must bring a Geometric Triptych from each planet. Placing all seven Triptych in the matching slots will activate the portal, allowing the player to interact with the Odd Stone in the center of the platform. Doing so will trigger the ending cutscene and credits.

The slots, in order from closest to the center to furthest, is as follows:
