...And Beyond
Ultra rare0.5%Pass through the Gateway Portal into the unknown.
The ending. Once any engine is awake you can shuttle up to the Unidentified Satellite parked near the sun; touch the Odd Stone on an outer platform to add it to the teleport network. Opening the Portal itself takes a second Geometric Triptych from every planet - all seven, each into its matching slot, which means all seven engines awakened first (
The efficient pattern: at each core, make two triptychs, slot one into the engine, then teleport straight to the satellite carrying the spare and slot it there. When the seventh ring lights, step into the centre and interact with the Odd Stone - cutscene, credits, and a shiny Galactic suit and palette for your trouble.
Leave anything you care about at base: vehicles and jetpacks don't work on the platform, and there are reports of parked shuttles going missing up there.
