The enemy that comes for you when you are in the clouds. The brotillery consist of a group of creatures (who knows what they are exactly) who will kidnap you and keep you prisoner in their dungeon. You can also hear their swords and armor clank in the distance when they come for you.
OH NO MAN I HEAR THE CLANKING DUDE! I THINK THE BROTILLERY IS COMING TO LOCK ME UP IN THE DUNGEON!
