För posten återskapade Buggers (AKA Formics) "Giant's Game" på Eros (vilket vid tiden för den andra invasionen var redan under jordkontroll) men på den närmaste livliga planet till jorden; Ursprungligen känd som "Ender's World" men senast bytte namn till Planet Shakespeare
In addition to recreating the shape and feel of the game world (out of concrete) in an attempt to posthumously communicate with Ender, they also left a cocoon with a fertilised female queen for Ender to find and take to a new world after humanity's fear of the Buggers had abated.
Enders uppdrag att demonisera sig (i hans medmänniskors ögon) upptar det mesta av 2000 års interregnum mellan "Ender's Game" och "Speaker for the Dead"
The hill was hollow. A deep depression in the middle, partially filled with water, was ringed by concave slopes that cantilevered dangerously over the water. In one direction the hill gave way to two long ridges that made a V-shaped valley: in the other direction the rose to a piece of white rock, grinning like a skull with a tree growing out of its mouth. "It's like a giant died here," said Abra, "and the Earth grew up to cover his carcass,” Now Ender knew why it had looked familiar. The Giant's corpse. He had played here too many times as a child not to know this place. But it was not possible. The computer in the Battle School could not possibly have seen this place. He looked through his binoculars in a direction he knew well, fearing and hoping that he would see what belonged in that place. Swings and slides. Monkey bars. Now overgrown, but the shapes still unmistakable.
"Somebody had to have built this," Abra said, "Look, this skull place, it's not rock, look at it. This is concrete.”

Only me, he realized. They found me through the ansible, followed it and dwelt in my mind. In the agony of my tortured dreams they came to know me, even as I spent my days destroying them; they found my fear of them, and found also that I had no knowledge I was killing them. In the few weeks they had, they built this place for me, and the Giant's corpse and the playground and the ledge at the End of the World, so I would find this place by the evidence of my eyes. I am the only one they know, and so they can only talk to me, and through me.
