After the fight with Guinevere, Nikolai had finally felt alone. Completely alone for the first time. It had frightened him at first to have this feeling, but the Sanctum's peacefullness was quick to quell his anxieties somehow. Whether it was because this was a place where Heralds were meant to be or for some other reasons, Nikolai was left to his thoughts to decide on what he was going to do.
The dreams here were far more vivid than they ever had been in the Human's world. Nikolai learned things he would not have otherwise and was presented with problems he did not know yet how to overcome. Silence once more came to him in the absence of other people while his only companions became his thoughts. There was never a time in the Sanctum he wasn't trying to understand what he was to do now. Jade was going to worry for him, probably think he was dead unless Guinevere told her where he was. But it would be better this way so she would never know what it was he had done to her and no longer hurt inside at the hypocracy of it all.
Now the ruins of the Sanctum had become his home, and though he fought at loneliness when he stopped to let his thoughts sink in. From where he was perched atop a wall of the ruins, Nikolai was beginning to wonder just what Guinevere and Jade were doing by now.
