Golana

Planet with an ancient time portal

A pleasant planet where Molly O'Brien falls through an ancient time portal and is stranded three hundred years in the past.

Golana is the planet where the O'Brien family goes for a picnic in Time's Orphan. While playing, eight-year-old Molly falls into an abandoned time portal and is sent three centuries into the past, when the planet was uninhabited.
The crew retrieves her, but the Molly they rescue has lived alone there for ten years and grown feral. Her parents eventually return her to Golana's past, where the older Molly sends her younger self back through the portal, restoring the original timeline.
