Lets narrow down who the Arsonist could be.
We know that Philie is the mayor so s/he can't be the arson.
We know that Illidan was jailed last night so he can't be the arson.
We know that Narks isn't the arson because his writing style is too complicated to fake and he knows who the masons tried to recruit.
I know that Admiral is not the arson because Sumikoko has been consistent with her writing style.
People I doubt are the arson:
Zack (he appears to know what Narks knows)
HerrZynich (Luna/Herr has that type of fun and it is my belief that it would be hard to fake)
Ambient (He's still stupid and I can hardly imagine someone faking that and getting it right)
Deathfire123 (He IS deathfire, but I can't imagine 100% proof that Fragos was Dark.Revenant)
More to come. I need to get out and about where I'm at IRL
