So David did prepare for this. He long ago had weapons made that are capable of killing the spirits. He also has safe houses in every city that can hold the entire population.

He'll be tossing up a post mentioning both and offering weapons. He'll also be sending units of GCPD Officers to the archways to help defend them on Genessia City's end at the start of the event. Guardians will be welcomed to make use of them or add their own ranks to the effort to help stem the creatures from getting through.
