"Don't worry about the eldritch horror, we've got a plan for this contingency — as soon as we've evac'd we'll just pop a brace of Storm Shadows on his ass and send him right back down where he came from."
— Captain Alan Barnes, The Jennifer Morgue
"It's a funny thing about the old gods. You think that just because they're old, they must be difficult to kill. But when the fighting starts, they go down just like anybody else. They're not stronger, they're just older."

Iris: To think I'd lose to a single mage fighting by herself...

See, cuz right now this is the part in any RPG ever where you have to kill God. It's pretty rad. I love killing God, I do it every day. You know, some people have breakfast, I kill God, with my super-giant house-sized sword, you know, it has 3 mortages in it, 2 families can live in it, but instead I use it as a weapon; it's pretty rad.
Chakravartin: You have exceeded my expectations. I praise you. You are indeed the one to inherit this world. Gaea must be led by one of its own. Now that you have become a perfect being, I may now leave this world, and save other worlds in need of my guidance. Come, and join your daughter (...) (extends hand) I am counting on you.
Asura: ...(extends arm) I refuse.
