About this project
What does The Lost Castle add?
Former structure of End Remastered, The Lost Castle introduces an enormous castle that you'll be able to find with the help of a map given by a journeyman cartographer. Inside resides infinite fortune and mysteries from a long forgotten civilization that disappeared a long time ago and is now eagerly guarded by illagers that won't give up on their fortune even if it means the end of them, or the end of you...
*Note that the castle is pretty rare and can spawn multiple thousands of blocks away from spawn.
