I'll post "humans" post after Darko comments, the moths will flutter away revealing the underworld once touched.

The White Moth Order will use one of the Forbidden books to summon a host of Valkyries and have them judge who is worthy of entering the temple by invoking the gods to mark their champions through the law father's servitors.

X will also speak in private council with the goddess of souls, no need for a separate room though, as she will be the only one capable of hearing him speak.

and the other two gods can draw their attention to the destruction as a taste of things to come for their champs.
