(I found Nick Dwyer's drafts about this. They were terrible. I deleted them from scratch and rewrote them. It was necessary. -Maiden)
Nick does not talk about this incident, or any of the incidents relating to it, because there is no good explanation. Even among those who have seen beyond the edge of the world, those who run in his circles, would dismiss it as being the fantasy of a lost soul. I can tell you however, without any shadow of a doubt that this story happened.
It is complicated. When this occurred is a time between when The Presence was kidnapped and when Nick became fused with Usurper.
Nick Dwyer was ascendant. He has overcome his past self when all design was made to force him to succumb. He did not mention this, did he? He was supposed to be the delivery system through which Usurper could act upon the world. In turn, he took Usurper and turned him into just another aspect. The first of seven changes.
In any case, he'd gained all of Usurpers talents. On the astral plane, He was faster, stronger, his senses were more effective, and most importantly he had become tough. Wounds that would have left him helpless with an unending migraine before would heal in minutes. There was nothing he could not defeat, at least, that was what he felt.
Two days after he was fused with Usurper, The "Rogue Wizard", in his own inimitable fashion, broke through his wards on the astral plane and killed his guards. Nick stood there in his shower late in the evening, completely defenseless.
This had not been the first time this would happen, nor would it be the last. If you want to put someone at a psychological disadvantage, even if you're only attacking on the astral plane, you attack them when they're naked or showering. Their mind is not focused, they've got water pattering on their skin which distracts one further, and they can't move with their physical body too quickly without causing a mess.
Perhaps that last one is not so important if someone is trying to kill you? I can't say.
For his credit, Nick just forced a grin and said, "I beat your thugs and broke your toys. Go home before I break you too."
And that was when Rogue Wizard threw a black knife. It struck Nick with such force, that his physical body actually collapsed in the shower.
For five minutes, the water pattered off of Nick's empty, lifeless shell of a body, before he breathed in sharply. Gasping for air he spent another five minutes laying there, praying to whatever gods he could think of that he might survive.
On the astral plane, spirits went to work. What they did not tell Nick was that he'd encountered one of the ancient weapons. You see, there are weapons in the world so powerful that they have transcended mere physical construction and become ideas. Longinus, Excalibur, Mjolnir, ideas potent enough that minor mystics call on them to defend themselves or attack their enemies in difficult times. Simply invoking these ideas correctly can make you more dangerous.
Nick Dwyer had been struck by Corruption. The idea wasn't invoked, it was literally picked up and thrust into his chest by someone actually capable of wielding it. You've heard the name Corruption several times over the course of all of this. Corruption would eat away at his insides, tearing him apart and rebuilding him as a monster with one purpose: the destruction of all life. At least, that's what the medics believed. That was after all, the fate of anyone struck by Corruption.
The Rogue Wizard had finally decided that if Nick Dwyer would not fulfill his original task, that he had to be eliminated. Without any doubt, this method would destroy him and take him out of the picture. The Presence had nothing to do with this.
This was also the first hint to everyone involved in our story that Nick Dwyer was beyond merely strange. After all, his body held the impact of Corruption in stasis at this point. As Nick pulled himself up out of the shower, and forced himself into bed, all entities prepared to kill him should he awaken as some sort of spirit devouring beast intent to feast on the world.
They were still waiting two days later.
And that was when Nick Dwyer received a phone call from Alan. ("Time Lord")
