Organization XIII was a group of thirteen Nobodies based in the World That Never Was who seek to discover the mysteries that lie within the heart and use the power of Kingdom Hearts to become complete humans once again. The Organization was first formed when the six former disciples of Ansem the Wise (Xehanort, Braig, Dilan, Even, Aeleus, and Ienzo) became Heartless, their Nobodies becoming the first members of the Organization. Members are numbered in the order in which they joined, with Xemnas, the Nobody of Xehanort, numbered one as their leader. Each member also has the letter "X" placed in his or her name. The remaining letters are an anagram of their name prior to becoming a Nobody. As Nobodies, they lack true emotion and morality, and are unable to feel guilt or remorse for their actions.
