Maroula has informed me that several people were in the Weapons Dealer that Pyromanche and the others were sitting on. They apparently went in there knowingly and shot off a couple of rounds of display weapons into the ceiling, sending the nanomages to reclaim at that time.
One of these was an Omni fixer, possible the same one that attacked Yarko a few months back. He used his ability to grid out to go un-noticed. He and his accomplice had knocked the shopkeeper unconcious, and did some damage to the store itself, including the holes in the roof.
So, although I still don't know who it is, we are getting closer to some type of answers. We have aquired the video tape from the store's security cam, and it is being analyzed by Dyan and Maroula, they hope to at least ID the accomplice since the fixer in GA will hard to determine who he is. If he is reading this and would like to possibly turn himself into Pyromanche or the NLF for questionsing, that would be most welcome.
As for the signal.. Maroula is applying for all new permits and after the manages to cut thru the red-tape.. I expect NMR to be back on the air.
