The XSA-23M Shadow Starfury was one of President Clark's smaller Shadow bio-tech derived secret weapons. The basic SA-23E Aurora Starfury was used as the base for this seedy project. The design is coated in Shadow bio-armor, which explains why Shadow spikes grew off of the hull. An elite squadron of Psi-Cops and Clark Cultists swore an oath to fight for President Clarks ideals to the bitter end. There have been several sightings of this elite "Black Death" squadron still in operation five years after the end of the Earth Civil War.
