At some point before he gets back to the begginning of Terra's adventure, MX finds an apprentice. Finally, just after Terra and his friends leave, MX gets to Terra's time, and attacks Destiny Islands. Eventually, MX calls on Kingdom Hearts to make Terra go into his final drive. But this time, makes sure that Terra thinks Aqua and Ven are gone, so that there will be nothing to guide Terra back to the light. It works, but MX is unaware that the good part of Terra was separated from him, and that part became the Kingdom Key. He proceeds to feign weakness, so that Terra will defeat him, and eventually become overwhelmed by his form. When Aqua and Ven try to snap him out of it, he calls them imposters and kills them. He then transports himself to Radiant Garden, and Aqua's heart is able to somehow extend Terra's dark portal to her armor, before her heart fades away to darkness. Because the dark portals were a new way of transportation, he loses his memory. Ansem finds him with Aqua's armor, has his apprentices help carry him back to the lab, and seals away Aqua's armor. Terra wakes up, and remembers only the name Xehanort, and so that is what he calls himself. At some point while doing an errand, he comes accross a set of armor, and suddenly he recognizes it, as if it were from a dream that he had. He eventually becomes drawn to that room, wondering why he felt the way he did around that armor. One day, he decides to obey the room's name, and sleep there. When he wakes up, he remembers. But he pretends not to. And that is where BBS will probably end. Now we will explore the Keyblade Graveyard.
