So, progress on Ghoulemberg:
After about a week and somewhere around 2 shipments of 15 stacks of 64 slate every day, I've gone through a bit of stone. The server's town has a quarry a ways into the mainland. It goes from a moderate elevation and down into the bedrock. It's about 24x26 blocks wide.
I'd say I'm about a third of the way done with the castle's structure. I've been stockpiling a large amount of books made from reeds grown just of the build site. I'll probably use all of the books for decoration. It's going to take a helluva lot of wood though. I'll try to get pictures later.
