Originally, there were meant to be two immortal brothers in the Valiant Comics Universe - Gilad, the Eternal Warrior and Aram the other, better known as Armstrong. Each is older than recorded history although Gilad is the elder by two years. In "Archer & Armstrong/Eternal Warrior" #8 (a double-sized "flipbook" that was two issues in one), readers learned there was a third brother, Ivar the eldest. Ivar then starred in "Timewalker", which ran for 15 issues. An extra origin issue, numbered #0, detailed his origin and childhood, showed his father Vandal, and explained why he was not present when his younger brothers Aram and Gilad were adults and discovered their own immortality.
