after going to the precursor planet, they returned to 4546B to live out the rest of their lives since they couldn't go back to a alterra owned planet after what Robin learned about them. they are both currently exploring a cave on land when they find a inactive precursor portal.

Robin: another portal. turns to AL-AN. know where this one goes to?

AL-AN: sadly I do not. But it would not hurt to see where it goes.

Robin nods and places a ion cube in the portal, powering it up. They walk in and after a few seconds they come out the other side. They look around to see where they have ended up.
