Mystic Castle.
It was one of the 'unexplored regions' of Trian Ruins.
Situated in the northern sector, near the great valleys, the great castle floated thirty-three miles above the ground.
It was first discovered during the 440s. There were several small-scale expeditions led by individuals. However, the strongest awakeners of these expeditions never exceeded level 7.
All these teams crossed the silver barrier and entered Mystic Castle. No one returned.
It happened again and again. Before long, the mystic castle gained a fearsome reputation.
There were other unexplored places too. But none as scary as this one.
Because no one knew what was happening inside. Through the silver barrier, you could only see the castle. You couldn't see the people even if they just went in.
So, the strategy changed.
