During the time of the Separatist Crisis, Obi-Wan Kenobi, a Jedi Knight, and his apprentice, Anakin Skywalker, a Padawan, found themselves deeply embroiled in a critical assignment related to a border conflict on Ansion, an event that greatly impacted the galaxy. After their return from addressing the Ansion disagreement, Skywalker and Kenobi shifted their focus to thwarting the plot to assassinate Senator Amidala.
The Ansion border dispute was initially introduced in The Approaching Storm, a Star Wars Legends novel from 2002 authored by Alan Dean Foster. This novel served as a companion piece to the 2002 movie, Star Wars: Episode II Attack of the Clones. The dispute achieved canon status through its mention in the previously referenced film.
