A hidden empire

Ozpin was contacted by Ironwood to help him with a very serious threat to both "Atlas and all kingdoms". Something or someone has been attacking and raiding Schnee transport fleets and vessels for awhile now. Buts what surprises him the most is when the he sends multiple airships to either escort, find, capture, or eliminate the threat the airships that have been tasked with escort duty never report back. Some even seem to be found outright destroyed. Some airships seem to lucky with they only have one hole that tell something forcefully entered it and the crew seemingly being taken.

This was not the work of Salem not even the white fang should be able to do this much damage. Theirs a new threat out there and Ironwood believes it's a threat to the whole world but is it really? Or could it be something else entirely, there's only one way to find out.
