I found an awesome looking place called Aurin today. Somehow, a dense, beautiful forest has appeared in the middle of a savannah! The forest is surrounded by clouds and lightning, and the forest is protected by dark creatures.
UPDATE: I figured out how they were turning my nice savannah into a magical forest; this nasty group of Eldan (species indigenous to Nexus) decided they wanted to turn my savannah into a forest, so I put a stop to it by deactivating their teraformer (see below). I do not care if the Eldan were here before or not; Nexus is the birthright of the Dominion!
Speaking of Eldan… Supposedly the story is the Eldan were here thousands of years ago and they invented the Mechari (which is just robots made to look/act like people). The story of the Eldan reminds me strongly of Battlestar: Galactica; humans created Cylons, Cylons rebel and fight back, humans have to leave their planet, etc. Anywho, very exciting stuff!
