Block City was Medivh's stronghold and his center for logistics and production.
The open-air blocks were mainly responsible for growing crops, raising livestock, and producing various foods and magical materials.

Goblin farming, for example, had already developed into an industry in the Wrynn Family's Block City.
Now, not only Black Furnace Fortress but also Block Cities in other planes, such as Ulan City, had underground ranches for raising goblins.

Logistics Skeletons didn't need any combat ability; Grey Bone Skeletons were enough.
Every year, the underground ranches slaughtered large numbers of adult goblins to reduce the population density. After the goblin corpses were processed, they were stored by month in designated underground burial areas.
Once they had aged long enough, the goblin bones were sent to the Skeleton Assembly Line first, where they were resurrected as Grey Bone Skeletons.
There was no need to store the bones of other intelligent races for aging when there were more than enough, but there was absolutely no need to do so with goblin bones.

Medivh's entire skeleton was Bone Spirit, and the Bone Avatars he split off were Bone Spirits as well.
Ever since he began smelting and resurrecting Resurrected Skeletons, Medivh had been studying the growth potential of
