A planet in the Demilitarised Zone where Ro Laren, working undercover in 2370, made contact with a Maquis cell that she would end up joining.
Ronara Prime is a planet in the Demilitarised Zone between the Federation and Cardassia. It appears in the seventh-season Next Generation episode Preemptive Strike.
In 2370 Starfleet asks Ro Laren, just back from advanced tactical training, to infiltrate the Maquis. Worf and Data set up a cover story by arriving on Ronara Prime to hunt for a Bajoran who has supposedly killed a Cardassian soldier. Ro, dressed as a civilian, lets herself be seen in a bar there and is quickly helped out of sight by sympathisers.
She is brought before the members of a cell, among them an older man named Macias, who comes to treat her as a daughter. After proving herself by stealing medical supplies from the Enterprise-D, she is trusted completely. When Macias is killed in a Cardassian attack, her loyalties shift, and she ends by warning the Maquis of Picard's trap and joining them.
