Slavik, who saw Hassan as a traitor to Kane, overthrew Hassan's leadership, while Kane simultaneously revealed himself to the Brotherhood. GDI, however, mitigated Nod's effectiveness by installing a puppet leader ( Hassan) over the largest splinter faction of Nod. This "disappearance" made Kane immortal in the eyes of some of the Brotherhood, which allowed Nod forces to continue operating even thirty years later.
Despite winning the First Tiberium War with the Ion Cannon strike on the Sarajevo Temple complex, GDI forces were unable to account for the body of Kane a singular fact that the GDI High Council later saw as a costly oversight.
Tiberian Sun follows Michael McNeil (GDI) and Anton Slavik (Nod) as they command Global Defense Initiative and Brotherhood of Nod forces during the Second Tiberium War.
