The Unground Boss Room.

"A dungeon boss room...?" Said John confusedly 

"In a way." Said Master Sylvia who stood on the wall besides the dark entrance they had arrived from. 

The words were direct and self-explanatory. Yet the confusion only grew, but before anyone could ask anything. 

Just as Master Sylvia had spoken, everyone's attention had been taking by the presence which stood in the middle of the large spacious room, just ahead of them on the other side of all the pillar platforms. 

The presence stood in the middle of what appeared to be the arena, a dark mass in the shape of a cube. A strange humanoid shape. 

A shadow? It most certainly looked like it. But no, it gave the impression of something much darker. And if it was a shadow, what exactly would it be the shadow of? 

A Dark humanoid shape with pitch-black crystals floating over it's back. The crystals resembled wings and was the only redeeming quality about that thing's appearance.
