Avil moss (pronounced ah-VEEL), sometimes known as lunar moss, is a type of plant that grows on the moon Abashmu and on small asteroids captured by the moon's orbit. There it survives on sunlit patches of rock, subsisting on the sunlight alone, which its dark green leaves are well-suited to absorbing.
The only creature known to eat avil moss is the culichnan, a squid-like animal.
Oddly, avil moss seems more adapted to terrestrial life than to its current existence in space. Samples of the plant collected by Eitan elven explorers and brought with them back to Kishar grew extremely well. It was not soil that led to this success, however, but evidently instead the presence of air. This caused some Eitan scholars to believe the moss is not actually native to Abashmu, or to space in general, but rather was left there at some point in the far-distant past.
