I did a lot of research last night, checking and cross-referencing things through a variety of tomes. I discovered that a Dark Magus is a versatile and flexible foe with a wide range of powers.
This is actually more useful to the town than you might think. It explains quite a few things and clears several people.
I am going to hazard a guess that the dark magus can not only take an apprentice, but that that apprentice takes up at least some of the original's powers. The "wide range of powers" would explain how I got roleblocked last night: one of the dark magus team roleblocked me while the other killed Reverie.
Now, my list of people I believe to be in the clear:
4maskwolf
ToonyMan: if he had been converted night one, he could not have used his revive night two, illusioned himself, and Persus performed the scumkill. That is too many actions for the scumteam. As such, I believe him to be innocent.
IronyOwl: there is no reason for him to give us this much information as a scum team member. It would have been far too easy to fabricate information to placate us, but the information we have been given seems remarkably accurate.
Now, the possible scum members, at least in my mind, from order of most scum to least scum:
Persus13: Only person other than Irony and ZU I haven't inspected, and those two are townie in my eyes and couldn't be the converter, respectively.
Toaster: Pending the man actually posting, my second scum pick because could have been converted N1 after my inspect.
NQT: The only charge I have against him is the obvconverter Persus knew what type of role he had. Other than that, after what Irony said, most of my accusations became invalid.
ZU: Can't be original, but if he is scum from the revival (highly unlikely) then we are at LYLO right now.
Let's go through the list of people, objectively, and see who could be the converter:
ToonyMan: almost certainly not.
IronyOwl: Probably not, for reasons stated above.
Persus13: Yes, could be converter.
notquitethere: second best option after Persus, barring a roleclaim.
Toaster: nope. showed up town the first night to 4maskwolf and the pm in question was confirmed by a now-dead confirmed townie.
ZU: Nope. Was revived.
4maskwolf: had his claim supported by Reverie that he targeted toaster with an inspect night one, so no.
