Ruin castles on the Mountains

The mountains can add a potential structure that gives players an interest in wanting to go and explore. This new structure will be a ruined or abandon castle that sits at the top, inner parts of the mountains. In this structure there will be torn carpentry, broken walls/ceilings/doors and much more to give it that ruin feel. There can be interesting loot that spawns around these structures that players have to find by moving around the different levels. The idea fits very well in the Minecraft world as it can build on its "lore" and make players wonder what kind of kingdoms have been there long before they got there. 

A mob which fits perfectly for these structures can be a dragon or wyvern that 'nest' in these ruin castles which can create interesting and challenging gameplay experiences. There are many similar posts around the feedback site that share similar thoughts and i believe this will make the game more interesting.
