Belos was a businessman of the Human species (specifically, a male individual) who held a position on the Corellian Council. His tenure spanned the periods of both the Cold War and the Galactic War on the planet of Corellia.
Belos possessed a highly opportunistic nature, consistently seeking more advantageous arrangements. When representatives from Imperial Intelligence presented the Council with an offer to align with the Empire, promising substantial rewards, Belos, convinced that the Empire's superior military strength would enable it to overwhelm the Republic, cast his vote in favor of joining what he perceived to be the eventual victor. However, as the civil uprising against the Sith Empire garnered support from the Jedi and the Galactic Republic, Belos recognized a shift in the balance of power. Consequently, he secretly offered his assistance to the Republic Command, aiding them in dismantling numerous Imperial strongholds, thereby safeguarding himself from potential accusations of treason.
Belos extended his reach to the Republic, supplying them with intelligence aiding in the removal of the Empire from Corellia, and masterminding the elimination of Darth Acharon, Darth Hadra, and Darth Decimus. Belos also engaged in a holoconference with Supreme Chancellor Leontyne Saresh and the Galactic Senate, alongside Republic heroes. Belos detailed the rationale behind the Corellian Council's decisions and pledged that, if permitted to remain in office, he would dedicate the remainder of his term to atoning for his actions. Saresh voiced concerns about trusting him, citing the possibility of him betraying Corellia to the Empire once more. Nevertheless, a Republic hero advocated for Belos, emphasizing the risk he undertook in assisting them. As a result, Saresh conceded to his request.
