If you were anyone else, things might be different. For a regular human to assist us, their mortal form is... insufficient. Yours is already immortal.

All we'll ask, if you choose to help us, is that you swear not to betray our cause. The consequences of which would be ones you'd welcome, not fear.

Oblivion.

But if all goes right for all of us - our sights are set on Heaven, for you.
