Mud, astronomical designation 978-1949890297, was a remote, barely Class-E world. Dry in the extreme, the planet derived its Humanic name from the smell of the sulfur that covered the surface. Likewise, the Gelt named the planet with a Mother Tongue obscenity for excrement.
At some point in the distant past, an alien race attempted to terraform Mud. It had a layer of organic matter, some of which was compacted to petroleum. Additionally, the fort occupied by the Gelt was identical to ruins on Ares in the Helios System. Additionally, the species had left a giant mech nearly identical to the primate-sized mechs that occupied the Queen Maria Sophia in a 433 IE incident.
