I'm sure I've lied so much over the past two thousand years that I could do it as easily as breathing. What you should be asking is 'can I trust what Ardyn is about to say?'

[The answer to that was almost invariably no.]

...I've nothing to gain out of going along with this game. Even if my current hypothesis is right and I might actually be able to die in a place like this, I've enough dignity left to refuse to allow that to be what kills me.

Killing any or all of you is, for now, inconvenient to me. The larger our numbers, the more resources available to us against our enemy.
