EQ history is a bit of a clusterfuck, the history of the Ogres from Crescent Reach just reflects the understanding that the Drakkin had of the event. Compound that with varying timelines and the whole Seeds of Destruction time loop thing or whatever the hell that was and there's no single "right answer."

On the topic of ogres:
And Rallos Zek returned to the surface, pleased with his sanction to create even more peoples for his army. He made then the Ogres, massive, unmovable beings of questionable intelligence, and the Orcs, bred for battle and singled-minded in their desire for conquest.
I think the Codex of War was eventually dismissed as "non-canon", but that Tome of Ages section looks pretty familiar from... maybe the boxed instruction manual?
