IV-89 is a really hot and sandy planet.. An Autobot scout had sensed a bunch of Decepticons there, doing shady stuff, so he went down to the planet, but didn't see anything. Just roaming around, casually getting attacked by Crawlers (Spiders except they evolved to the climate) and Flyers. (Basically like Vultures except more scarier and evolved) Just to be honest, the days and years are longer than every other planet in the system, they make you want to scream.
