The Ultimate Vampire Resource and Directory

Sandstorm was an Autobot among those Autobots who peacefully settled the planet Paradron. Outnumbered and fleeing from the Aerialbots, Cyclonus and Scourge took refuge inside a vortex, which transported them to the pacifistic, energy-rich planet of Paradron, which had been settled by Cybertronian refugees. Naturally, the duo immediately overthrew the planet and summoned Galvatron and the other Decepticons there; the plan was ultimately foiled by the Autobots, but at the cost of Paradron itself, which was destroyed.
