'Kill?'
Images of the altar mixed with Juls and Amelia's blood. The altar stood in between 6 candles, in a dark and desolate throne room without a king. Nick was back in this place, standing before the altar.
Beyond it, he could see 8 more like this. They stood like immovable objects, refusing to yield to anything. As if they were stopping something from reaching the empty black throne—or reaching it. 8 untouchable walls.
Seals.
That's what each of these were–seals. Seals of Annihilation, to be exact.
A concept that Nick knew for a fact wasn't a part of the game he knew. When he first saw this place, before entering the Special Dungeon, he had thought it was just a dream or nightmare.
But Amelia's blood wasn't fake; Juls' wasn't. A sea of crimson flowed within the First Seal, stopped only by some invisible walls created by the candles.
