Rimba

The planet Rimba was inhabited by the nomadic species known as the Guerners for several centuries, after they arrived there in their Guerner Transport Ships. After exhausting its vegetal resources, they repaired their original Ships and built more, and prepared to move on to a new planet. The Second Doctor materialised there by chance just as the preparations were beginning, and he stayed for two weeks, helping with the ship-building and joining in the celebrations.
