Cauldros (Japanese: 黒鋼の大陸, Kurogane no Tairiku lit. Land of Black Steel; English dub: /ˈkɔːlˌdroʊs/) is a region in Xenoblade Chronicles X. It is where the Ganglion have established their main stronghold. Cauldros lies to the north of Sylvalum. The volcanic terrain is broken by pools of molten rock, ancient battlefields, and the ruins of an ancient city. Due to the hostile terrain and at times hostile weather, it is the most difficult region to explore. __TOC__
