Surd is the name of one of two artificial moons that orbit the moon of Mongo. Along with its brother moon Arkaylia, it was created pre-Great Sorrow for the use of shelter for travelers that came to mine the moon for its riches. Surd was also used as a place to process the Zerilium that came from the moon.
