The Yarlubb river coursed through the wooded moon of Endor, situated in an area that lay between Bright Tree Village and the Red Bush Grove. It is known that Leektar at one time tracked along this river as he looked for a new settlement after his own had been razed.
The Yarlubb river's existence is attributed to Arthur Papadam, who created it as part of the What's The Story? story about Leektar.
