Ashes of the West
The aliens left many examples of their technology behind. Both the Coalition and Freehold have had interest in collecting these relics, for both examination and repair. Alien weaponry is varied, with a multitude of colors and and designs, and as many effects as can be imagined.
Less is known of non-weapon technology, as it has survived mostly in the odd shield generator, broken shuttles, and the private and illegal collections of the wealthy.
From the weapons technology recovered, it can be assumed that the aliens had hands similar to those of humans, and bodies of a similar size.
