Golana

Golana is an inhabited planet near Bajor. It was once home to an advanced species who used time portals, but who vanished around the 14th century. In the early 24th century, the Bajorans colonized the planet. 

In 2318, Minister Jas Holza expressed interest in the Cardassian proposal for the Bajorans to be given technology to increase the speed of their starships, remarking that it would bring Golana much closer to Bajor and be a benefit to its inhabitants. 

In 2372 or 2373, Miles O'Brien, Keiko O'Brien and Molly O'Brien visited Golana. In 2374, they travelled there again, this time with Kirayoshi O'Brien and enjoyed a picnic. Molly wandered off and fell through one of the time portals, which sent her back in time to the 21st century. She was rescued, although ten years had passed for her. Miles and Keiko were initially unwilling to send the adult Molly back and erase her from history, although they soon realised she would never be able to completely adapt to society. Helped by Odo, Miles and Keiko returned the adult Molly to Golana, where she travelled through the portal and showed her younger self how to escape.
