Dark wings flew over the blue waters of the oceans. They were easily a kilometer across and 100 meters thick at the center mass. There were dark glass sections looking out but did not let anything in.
A team of 20 Fiends were rotating keeping the Raptor in the air. The farther from the continent they were, the larger the team they needed. The artifacts were created in batches for mortal realms where flight was heavily restricted.
Sky Realms above tier 5 could usually break it but it was rare to send so many valuable powerhouses to a simple mortal realm. They had better uses in the Heaven Realm for the war.
Thus the Raptors were crewed by only Tier 2 to 3 Sky Realm Fiends that were inefficient to keep the advanced artifact flying. Still, the Raptors were effective intimidation for the populace and to get around quickly.
Teleportation arrays for such a mortal realm were unnecessary on a single continent when they turned it into a simple farm.
