Knights Eternal II Story

Knight left and found a desert in Eternal II where he built an underground base, then a humongous castle. Knight had found the remains of a horse one day. The collar said to look in the town Sandhill for a man named Dakata. He gave the remains to him and didn't ask for anything else in return since it's a pet of his and only a complete and udder terrible person would need something in return for it. One day, someone named Setsuna met him at his castle. She gave Knight a false note from Dakata and asked for help in a war. Knight agreed to have her owe him a favor and she left. A few months later an old friend of Knights greeted him, it was Gabe. He told Knight that he stopped being corrupted by the stick and Knight gave him a place to stay, though he still felt off. A few days later, Knight was searching when he felt the presence of the debug stick. 

Knight went to Sandhill and met Mikey, who had also encountered the stick before and was looking for it too. They agreed to help each other in case of the stick. A few weeks later Knight was fed up and talked to Gabe about it; Gabe would get frustrated and in a fit of rage killed Knight. He took over the castle and Knight went in prepared to kill his friend. Gabe and he talked, revealing that he was talking to the stick the whole time. Knight didn't know what else to do so he had Setsuna explode the castle for him as a favor after the battle that they totally had. They both died and Gabe was back to normal.
