As the three travel through several worlds, Terra attracts the attention of several villains, who offer him the whereabouts of Xehanort in exchange for assistance in their own agendas. He eventually finds Xehanort, who offers to take him in as his apprentice and urges him to use his inner darkness to gain power. He further instructs him to destroy Vanitas, the source of the Unversed, who was created from the darkness extracted from Ventus's heart.[30] Shortly afterward, the three friends reunite at Radiant Garden, but a schism forms between them when they have an argument over Terra's presumed actions in the other worlds.[31]
