When talking with
Nicodemus assures this character that his plan will keep them "safe from the Enemy". Was he referring to God, Nicodemus's traditional chief enemy, or was he talking about
We know the latter has been rolling in circles that Nicodemus and Co. frequent, and could make his statement actually not misleading.
It seemed like he was promising Deirdre that she'd avoid God's Judgement by leaving her to face Hades's. Could he have instead been putting her in one of the few places that we can be nearly sure the Outsiders can't reach? The Underworld is used as a mixed high security prison and armory against the Outsiders, it's got to be as safe from Nemesis as one can be, except at peer locations like Arctis Tor, Demonreach, etc.
Edit: there are other people that this character and Nick both hate, but they're unlikely to get a capital E in Enemy.
