This modifcation contains the new polder (=reclaimed land) biome. This biome has big trees, thick marine clay soil and a few remaining houses from a long gone civilisation. The biome also has a new tree, which can be used to make a new type of wood: willow wood. This wood can be made into doors, stairs, fences etc. using the standard vanilla recipes. Underground underneath the biome are 2 unique ores that only spawn in this biome: marble and dicalcium silicate. The marine clay soul can be dug up to make into 3 new brick types, that are almost fully blast resistant. The new brick types are stronger than standard bricks and can be used to better fortify bases. Underground a rare structure spawns, which is an ancient city hall, which was the last resort of an ancient society. Great loot can be found here.
