Muur represented a core food source for the Yuuzhan Vong, being derived from yeast. Despite its widespread consumption, its flavor was generally considered unpleasant.
To prepare for the impending invasion, Yuuzhan Vong advance teams cultivated significant amounts of both muur and lambents on Shramar before the breakout of the Yuuzhan Vong War. This was done to provide sustenance for their forces.
