Heptes

Heptes, the (rather unoriginally named) seventh planet in the Enere system, is a large, rock-covered, surprisingly hot wasteland, almost the exact opposite of its orbit-mate, Glacia. It is here that the HAEN Rebel Force set up their base of operations. They were stopped by Ender, who sent them back to Terra.
It is also the resting place of the Pincer Arm of the Legacy Beast.
