The castle called Dragon's Hearth has been the subject of many legends for many years. Surrounded by the highest mountains of the continent and with extremely high walls it is the strongest fort of Dragonia. the inner wall is protected by 7 enchanted dragonstones(stones that are formed when a dragon dies under a full moon), enchanted by the 6 high mages and the second dragon king they make the wall unbreakable and protect it from any magic. the gate in the outer wall is protected by a dragonstone enchanted by the dragonian king himself and 3 ballistae in front of it.

Many battles are said to have been fought here and a prophecy speaks of a huge battle that will take place here when the dragonian king returns. It is a popular destination for travelers because of its spectacular seize and the many books that have been writen about it.

This build features:
-an amazing landscape( as usual)( might just be a bit exaggerated)
-a keep partly hidden behind the huge wall, only accessible through a secret entrance 
-a big outer wall with a working redstone gate
-some siege weapons
-a docking tower for airships( 3 small ones and 1 large)
-a random green portal

I will probably build a town around it later
