Ancient sands

Ancient sands is a biome available in both Terralith 2.0 and Terralith Legacy, where Sand and Red sand mix themselves in wavy patterns through the whole biome. In Terralith Legacy, you can find copper pipes coming out of the sand, maybe from an old civilization that exploited the amount of copper ores under this biome. In Terralith 2.0, those patterns can be Sand patterns on Red sand or Red sand patterns on Sand, Terralith Legacy only had Red sand patterns on Sand.
