OK, it makes sense when we're talking about 1 vs 1 fight of titans, but fixing veil seems more like a chore- you take that pile of source and put it back into veil so it's not torn anymore.
However Lucian is already divine and from fighting perspective he was weaker than 2 regular Black Ring minions (while Braccus Rex was really wreaking havoc each turn), i'd expect combined power of 7 to be more than this. Also Lucian is divine which means that he bathed in the source lake and it's supposed to be enough to go against God King, while 7 gods still had all that power of the lake unused, so why didn't use that instead of making Divine? I really can't grasp the idea of what is the value of source really. Like the lake of source is so super powerful mythical thing that just touching it grants you amazing power while on the journey you find 2 or 3 huge tanks of pure source and noone makes a big deal out of it and don't even think about transporting it to Lady Vengeance, bottle it or whatever.
