Dabbling In Darkness
About a decade prior to Kingdom Hearts, Aeleus was one of six apprentices to the ruler and scientist of Radiant Garden, alongside Xehanort, Braig, Dilan, Even, and Ienzo. Worried the Darkness in people's hearts would eventually consume his world, Ansem began performing tests on Xehanort's heart. Eventually, he created a laboratory in his castle's basement for such experimentation. However, Aeleus and the other apprentices had their own intentions for the laboratory, and began conducting inhumane experiments on the human heart and the darkness within it. Such experimentation led to the creation of Heartless. Ansem quickly discovered their secret experiments, and immediately ordered them to stop. One day, after being advised to review their research data by King Mickey, Ansem found that the effects of their experiments had become irreversible.

Eventaully, Aeleus and the other five apprentices dabbled too deep into darkness through their continued experiments. Aeleus, along with the others, was consumed by the darkness, producing a Heartless. However, the apprentices all had strong wills, and so Aeleus also became his Nobody, Lexaeus. The six Nobodies formed Organization XIII, and banished Ansem the Wise to the Realm of Nothingness.
