I agree with you with almost everything, especially the one with Makarov and Lumen Histoire, I too think that if it is used the one who used it dies.

When Mavis said it was the Guild's "Light" and Ivan said it was the Guild's Darkness, I think now I see what he meant, he thinks Lumen Histoire is a fail safe weapon in case if everything else fails and it is an absolute last resort because kills the caster, and it goes against Fairy Tail's beliefs where no one dies, they live.

But the main question is what it will be used for, on E.N.D.? or the 2000 Faces. because if it has anything to do with E.N.D. then he would be expecting something like that and would not show himself till after it activates. that's what I think anyway.
