Mirror, Mirror possibility....?

[vincentric]

I wonder who will be the Warden when Harry gets sent to the Mirrorverse?

If the position is open, then he could retreat there for a hideout.

Would there be different entities imprisoned there? Harry leading a small jailbreak would be a good way to find enough allies to stop Evil Harry.

Also will Harry be able to contact Uriel? Just a hint of information could go a long way.

I doubt there was a Warden, there hadn’t been one for decades. No one used Demonreach for years, even when Morgan was being chased by a Naagloshi

Harry could repeat the Sanctum Invocation, but I wonder if Demonreach is aware of its doppelgängers as Mab is supposed to be. Given that it was built simultaneous in five time zones, the answer is probably yes, to prevent escapes to alternate time lines.

Unlikely to be different entities, the nexus point is Harry’s decision in Grave Peril and no Warden has been available for decades before Harry.

This means of course we could find out who the English Prisoner actually is without the English Prisoner being aware of it, or have him released on that timeline.
