Ending Their World starts as soon as you accept the quest from Demolitionist Legoso. You have to escort him and keep him alive during the entire quest.
This quest is only available to draenei players.
Follow and protect Demolitionist Legoso as he attempts to destroy the Vector Coil and slay Sironas. Return to Exarch Admetius at Blood Watch should you complete the mission.
Don't accept this assignment if you value your life. You see that gigantic power core jutting out of the mountain side over yonder? Whoever takes on this burden will need to fight their way through that mountain, battling an army of Sunhawks while protecting me as I rig the core up for demolition. Sironas the eredar is somewhere up there as well.
I won't think less of you if you just walk away, <name>.
But maybe you're the one - the one to destroy the Vector Coil and take down Sironas. Well, are you?
Is it done? Are we victorious?
You have saved the whole of Bloodmyst and Azuremyst, securing the Draenei way of life on Azeroth, <name>! For this, there can be no amount of thanks, no reward, nothing large enough in scope to truly express our appreciation.
Yet, there are still so many that were left behind on Draenor who cannot be here for this historic event. You must find your way back. Find your way back to the Outland, Hero of Argus. Bring our people home. Home to the land that you saved. Home to Azeroth...

Upon completion of this quest, an announcement is made to the region and Bloodmyst Isle's major NPC's and questgivers assemble outside the tower's entrance to honor your accomplishment.
