@WAAARGHbobo, "I am not your enemy. I am the enemy."
Is that a biblical reference?
It seems to me that the 5 darkin reference the four horsemen of the Apocalypse.
Aatrox being war, He loves and thrives on battle and wields a sword like the horseman of war is depicted to.
Rhaast is Death, He has a skeletal face and wields a scythe, he takes joy in slaughter and killing more than the fight itself.
Varus is plague, He wears a crown, a bow, and is inhumanly beautiful. The plague horseman is depicted with a crown a bow, and occasionally as beautiful and princly due to being occasionally depicted as the anti christ.
Then i would presume the next two are Famine and God's Lamb which is said to break their seals in the days of the Apocalypse.
The quote from Aatrox, "I am not your enemy. I am the enemy." Seems to drive this home for me.
In the bible Heylel, or the roman translation Lucifer, was an angel of light. Upon rebelling against god and being cast out of Heaven he bacame known instead as Satan, or Ha Satan, which means "the enemy".
Am I just seeing things that aren't there or is this your intended direction with the Darkin?
