1-Sil 2-Chris 3-Zero 4-Erin 5-Russ 6-Ray 7-Someone Bliss thought was dead (Richard Eno? Truedream? Owen Greylash? Silver? Vorden? Borden? Sam? Peter? Vincent?) 8-? Quite the impressive force that Quinn would have at his disposal - assuming that some of them could restrain themselves from killing their allies long enough to focus on defeating the real enemies in front of them (looking at you, Erin).
May not happen but if Quinn gets the message he’d pop in, say something like: “So that’s who you guys are afraid of, good to know and to see we actually have a few enemies in common.” And even though he left already, what if Quinn used celestial energy to add his shadow power to Sil who may even feel it when it happens. It has been said to be a God Slayer power so it would be perfect for him. His ability and most of all his unique soul weapon would make it possible. Also if any celestials came for him Quinn could travel to him instantly, defeat whoever it is together and drain their energy to make up for what was used to do it. Then travel back to Alex when it’s done.
Who is thought to be dead, and also had been close enough to now be a godslayer… obvious choices Richard, arthur, Leo someone from rays time… owen? Make sense he could have faked his death he may be my number 1 choice. Jim, the dalki, TD, or that mind altering guy I guess could be options, probably whoever is the leader of that cruise line, but I really hope it is owen
The list seems quite short or are dedicated followers or those using celestial weapons not counted. Like Peter and Layla should be a safe bet for Godslayers level. As for the one she thought was dead I wonder who only Leo makes me think of someone who could reach Godslayer. Borden is also an option but I don't think Bliss would miss him.
