Scaldron

Not much is known about Scaldron but those who have watched the enemy spotlight video know that it is a desert planet, no known heroes come from it, and it has a variety of genesis types for enemies. When Maxis made the video, more people started to learn about the planet. Maxis may have released some (hard to find) concept art before the planet's name was known but the primary source of information is the video on Darkspore.com (and this wiki).
