Ender's Teacher

While on planet Eros, Colonel Graff was ordered to stay, protect and take care of Ender for the period of time he had to be there. Due to the isolation, it caused Ender to focus on his studies. When he wasn't doing his work he would play with the battle stimulator which he had played so often he passed 15 levels and there was no challenge anymore.

The next morning when Ender awoke, instead of seeing Colonel Graff he saw an old man. The room was filled with silence while the old man relaxed and Ender did his self-defense exercises. By his surprise, Ender was soon on the ground due to a kick from the old man. When Ender didn't respond, the old man attacked Ender again and soon both of them were fighting. The old man introduced himself as Mazer Rackham who was the commander of both bugger invasions and his duty is to train the next commander. Both him and Ender spent a lot of time together watching the uncensored videos of the bugger invasions, thinking of strategies to win the Third Invasion.

Mazer spent time explaining important facts about the buggers to Ender. One major fact is that there is a Queen, once she is killed, the rest give up and die. The other fact is that killing doesn't matter to them, they just want to have a species left. Mazer also teaches Ender about the Dr. Device. A machine that sends out a sphere shaped field of molecules that can explode ships in a chain reaction. Ender practiced 10 hours learning how to command a fleet every day with all of his friends and best soldiers from Battle School, including Petra, Dink and Alai. They won every game and progressed each time. Mazer said he wasn't going to give any pity to Ender.

Every night Ender has nightmares about the giant's corpse, the buggers and the stimulator. One night he woke up with a bloody hand because he had been gnawing on it in his sleep. The doctors bandaged it up, but a few days later Ender was very ill. Due to this, he stayed in bed for three days, having terrible nightmares then returned to fight more battles, which he had won. Then one day nobody was in his room when he woke up, so he got ready and went to the stimulator room. Inside the room, there were many men, some that he recognized and others he did not. Mazer told Ender that he was going to have his final examination that day and he was not going to take it easy on him. Mazer informed him that there would be new challenges to overcome as well.

Ender was annoyed of feeling corrupt and destroyed and felt like giving up. He wanted to fail so he would never have to play another battle game ever again. There were so many enemy ships that Ender decided to take the chance and go for the planet without any special formation. His team helped him out by following his commands and blowing up the planet using the Dr. Device. Ender was just happy that they had won and the text was over. After when everyone was cheering, Mazer told him that the battle was the real Third Invasion and they had won. Ender was glad but so exhausted that he went to bed and fell asleep. Mazer and Colonel Graff tried waking him so they could get him to safety. The Russians, Hegemon, Warsaw Pact and the Americans were all fighting and want Ender to run their governments, except Warsaw Pact. Ender didn't care and just wanted to sleep. While he was sleeping he had another dream, but instead of seeing himself as a killer, he was just normal. Later, his friends came into his room and told him that they had won the war and that everything would be okay. The only problem is that none of the kids knew what they would do with the rest of their lives now they weren't preparing for Battle.
