A crossover between "The Bridge: A Godzilla-MLP Crossover" with the Amalgam'verse and "Fanning Our Flames" with the Shimmer'verse.

When warlocks in an alternate Equestria, working for a remnant of Nightmare Moon's cultist army, reach through the aether to bring forth all manner of creatures to fight for them; they tend to bring in the darndest things when the retrieval spell gets thrown off balance due to an element bearer's interference.

And the attempt to revive an ancient Equestrian evil isn't the only thing to worry about this time around for the 'Shimmer'verse'...
