Civil war born of a split in faith officially erupted within Karabor Temple City.
Archbishop of the Holy Light Yrel was furious, and the two naaru from the Holy Light Legion likewise disliked the new theory of the Holy Light proposed by Prophet Velen from the main timeline.
Thus, the Lightforged Judgement Army quickly declared Velen from the World of Azeroth a heretic. Any fellow countrymen who followed him would be branded heretics as well. The justice of the Holy Light would endure!
As the Lightforged Judgement Army formally entered the fray and joined the street fighting in Karabor, the Draenei of Velen's faction instantly fell into a disadvantage. Barricade positions fell one after another, and the situation became critical for a time.
But as the saying went, a good man needed three helpers. Velen had grown wise with age; having navigated society for so long, all the way from Argus to Azeroth, what storms had he not seen?
So you called for backup, huh? Fine, just wait there. I'm making some calls right now. Anyone who runs is a grandson!
And so, Velen the old hand picked up his beloved communication crystal and began making calls—otherwise known as summoning backup.
"Hello, you there? I'm getting beaten up in Karabor. Come help me!"
At this moment, Velen's experience as a worldly old elder showed itself. His network of connections was incredibly extensive.
The Alliance brothers next door, who had been holed up in Vanguard Fortress eating snacks and watching the show, received the call. They stopped eating, rolled up their sleeves, and were the first to join the battle.
The Dawn Brotherhood of the Stormwind Kingdom declared that Dawn Knights and paladins were one family. Now that the Holy Light was in trouble, Dawn's Light had to lend a hand.
