Ardleon is/was an angel of the High Heavens.


Ardleon fought beside Tyrael in a battle of the Great Conflict. He was forced to call for aid, and Tyrael, despite being poised to deliver a killing blow to Azmodan, came to his comrade's side.

The event would haunt Tyrael's memory even thousands of years later, reflecting that if he had struck Azmodan down back then, the Lord of Sin would have never brought his forces to Sanctuary. However, the Nephalem pointed out that it was never wrong to save the life of an ally. Tyrael, having become mortal by this point, agreed.[1]
