About this Mod
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.
