Kir Gendu XXIII was born in 463 GD, and ascended to the throne of Emperor of Aden in 494 GD.

He was assassinated by Vincent Thompson by the order of Kir Gendu XXIV.

Kir Gendu XXIII is remembered as a horrific despot and warlord whose reckless use of Adenian armed forces for expansion (especially former Kalts) is remembered as a domestic genocide.

Additionally, the use of nuclear weapons by Aden against Teth during the war is regarded by historians to be a horribly dangerous and pointlessly destructive example of using military might for political posturing.
