Colonel Graff

Later on, Colonel Hyrum Graff appeared on Wiggin’s doorstep and offered a special place for Ender in the Battle school, a school for the training of young children to become soldiers that will one day fight against the Buggers. Colonel Graff told the other boys that Ender was far superior to them and made him earned many enemies from the start. For Ender, the training was tough. It felt so lonely but he found friends. He tried his best to be promoted in the difficult training scheme and he exceled because he is just smarter than everyone until he was promoted to his first training army, Salamander army which he met Commander Bonzo, who dislike him a lot. Then he met Petra, who taught him how to shoot for the zero-gravity laser tag game and
some battle room techniques. Ender practiced a lot and later on he was given his own army for the laser tag game named Dragon Army. Through his superior leadership and training skills, he works up Dragon Army into a victor. Ender even beats his old commander, Bonzo. Ender has killed both Stilson and Bonzo, though Ender doesn’t know this until later. He met Mazer Rackham who introduced himself as his teacher. He explained everything to Ender, how the buggers killed millions of people in the first invasion, how they will win and about the new weapon. Until Ender’s final examination came which is a simulated battle. Ender together with his subordinates won the third invasion the League war resolved. Ender felt so lonely and tired from everything but he continued. He just killed off an entire species of Buggers. Everyone was cheering, crying and hugging each other.
He was confused and Mazer admits that for the past few months, Ender hasn’t been playing against the simulations but he’s actually been fighting against the buggers. Ender was comatose for how many days. When he woke up, his friends were surrounding him and congratulate him. Graff was tried but found innocent and become a become minister of colonization. Ender was left in Eros because he would be too dangerous if he comes back to earth for people wants to manipulate him. He also watched Graff’s trial and learned about Stilson and Bonzo. He felt bad for all of the deaths he caused and felt much worse than all the people he killed. He was working on the colonization ships that are going out while stucked in Eros. Then Valentine came and convinced him to go with her and figure out what the buggers were like based on their remains. While looking for a location for a new colony ship, he started to recognize the place around him as the giant's corpse from the Fantasy game. It appears that the buggers built it for him and discovered that they left him a queen pupa. Through telepathy, Ender and the buggers were able to communicate with each other and they told Ender about their history and how they are sorry for all the deaths they have
caused. They also said that they forgave humans for killing them. Ender wrote a novel with the point of view of the queen. He signs it “Speaker for the Dead” which is also the sequel of this book. This was the inspiration for eulogy to be born. Because of the queen pupa, Ender was able to restart their species. Together with Valentine, they started looking for a place in different planets for the buggers to live and grow its population.
