Noble knights were practical. As long as their core interests weren't harmed and there was money to be made, they were happy to cooperate.
Medivh was a Necromancer certified by the Church of Light and licensed to conduct archaeological excavations. Selling him bones wasn't illegal.
They had even sold him the bodies of Indigenous people who had been given only a simple burial, and he had passed them on to the Wrynn Family.
They marked the locations on a map and let the Number Two Bone Spirit Substitute dispatch skeletons to dig them up.
With the war over, Loran and the other city-states began large-scale migrations to cultivate their territories on the plane.
To make archaeological excavations easier, Medivh requisitioned a batch of Alchemy Airships from the Kunpeng Merchant Group and had them sent to the Kazma Plane.
The Alchemy Airships could carry plane migrants as passengers without requiring much additional energy for the transfer. The Loran City-State Council helped transport them for free.
Medivh knew how to show his appreciation. Some of the Kunpeng-class Cargo Airships sent to the Kazma Plane were assigned to help the various families transport plane migrants free of charge.
The rest of the Kunpeng-class Cargo Airships followed the Archaeology Skeleton Corps around the various plane territories, transporting the bodies of the Indigenous Allied Forces and historical remains buried deep underground back to the Barren Mountain Region for storage.
During the mass migration from the Loran City-State, Medivh transferred a million Logistics Skeletons to the city-state. They were packed into Kunpeng-class Cargo Airships and sent to the Kazma Plane.
Some of the million skeletons followed the Archaeology Team around, digging up bones. Others cultivated fields and built districts in the Wrynn Family's plane territory.
Medivh named the territory on the Kazma Plane Black Furnace Fortress.
