Muraganda is a plane that first appeared on the futureshifted cards Imperiosaur (flavor text) and Muraganda Petroglyphs. It is featured as a plane in Planechase (2009), on the plane card Feeding Grounds.
Little is known about the bizarre entity that crawls the world of Muraganda. The fang druids call it the Mimeoplasm, as it absorbs the traits of anything it engulfs. The saurid warriors of the suth seek out the Mimeoplasm wherever it roams, believing it to be the key to a mysterious afterlife, hoping to see in it traces of their fallen loved ones. The elves of the tropics believe it to be part of nature's cycle, a way to channel death back into life. The scarwitches hiss when it approaches, seeing it as the ultimate enemy of the world. Whether it's a natural process or a malevolent force, the Mimeoplasm never fails to command respect.
