Pyro V is the fourth planet from the sun of the Pyro system. It was given the classification of "Pyro V" when researchers came across strong evidence that its outermost moon once maintained a stable orbit around the system's star between Pyro III and Pyro V. When Pyro IV was struck by an unknown celestial body, it was knocked into Pyro V's gravitational sphere of influence. Residents of and travelers through the Pyro system are known to harvest hydrogen from Pyro V's green and yellow atmosphere.
