Building on Mountains

Mountain seeds are perfect for building. You can carve into the mountainside for a base, use natural peaks as watchtowers, or build massive structures across multiple peaks. The exposed stone and varied heights make for interesting architecture. Mining is easier too since ore veins are often exposed on the surface.
