Galactus

24 hours before the attack of the Arcadia city,

In the black darkness of space, a cruiser class starship had just come out from hyperdrive as it zoomed into a new galaxy at the speed of light.

On the bridge of the spaceship were a dozen black uniformed humans hunched over behind their individual computer screens, operating the ship with intent looks on their faces.

"Captain, we have successfully entered Galaxy D-762"

"Well done, proceed with scanning"

There are 9 known realms in the universe, each with its own thousands of galaxy.  This particular one resided within the Chaotic ones. 

It was considered a chaotic realm as it's not considered a part of any of the human occupied realms, nor was it part of any of the elven realms.

"We have allocated the last known location of Prometheus ship of the Grey wolf"

"Alright send a message and set course to location"

"Yes captain"
