Remnant

A remnant is a biomechanical entity resembling a linen bandage or strip of cloth. Engineered on the planet Desolation by the locals at the "behest" of the Stenza (read: at gunpoint), remnants served two purposes. The first was hiding in piles of bandages meant for enemy wounded in order to kill them, and the second was to gather information about enemy plans and report back to the Stenza (this is where their intelligence and psychic ability comes in, which they have later turned toward taunting opponents with the information they have gathered telepathically). The espionage elements were later recycled into Gathering Coils, which were widely considered to be a lot less mouthy, as gathering coils cannot speak.   Remnants were among the weapons of war that survived The Burning of Desolation, along with the flesh-eating microbes which are byproducts of many of the experiments and had to be flushed as a result. With the planet rendered uninhabitable, the remnants fell into dormancy most of the time, only animating at night to roam the planet looking for the poor unfortunate souls who happen to find themselves there.   Ta'zhen is said to have encountered remnants during her Citizenship Trial, although she was likely too in shock by the injuries to her arm to remember much of the encounter.   During the final Rally of the Twelve Galaxies, Angstrom wounded a remnant that had snuck up on her competitor Epzo while he was injured and sleeping it off.
