Great Wall
Great Wall is a wall about 10 tiles thick around the Core, on the outer edge of ring 2, about 400 tiles out. It wanders between 350 and 450 tiles at the default Chaos setting. With Chaos Off the wall is an exact circle. Low narrows the band; High and Extreme widen it.
A wall you cross, not a place you farm. Mining skill does not count Great Wall tiles.
