Two of the crystals glowed with a freezing blue light, their surface crackling with icy energy that seemed to suck the warmth from the air around them. The cold emanating from them was so intense that the room's temperature dropped noticeably, causing a thin layer of frost to form on the bed and nearby furniture.

The shadows in the room stretched toward the crystal as if drawn by an invisible force. Looking at the crystal that was emitting an oppressive dark aura, Nox couldn't help but think the crystal gave off a similar aura to his master Eve.
