This won't apply until Street Grimoire becomes legal, but I have a question regarding the Containment Zone background count:
Between the Cermak Blast, the bugs, the debilitating effects of FAB III, and years of death and metahuman misery, astral space in and around the Zone is horrible. Unless otherwise noted in the scene, assume a default background count of 2 anytime characters are within the Containment Zone.
Is the Containment Zone considered to be aspected towards "violence and war", which would allow the Domain of the Warrior metamagic (from the Warrior's Way) to apply to the Background Count?
Also, would the worship of insect and toxic spirits in the area make it aspected with "religious or spiritual significance", which would allow the Domain of the Spiritual metamagic (from The Spiritual Way) to apply?
Once Street Grimoire becomes legal, those questions are going to need answers. Personally, if I had to make a call as a gamemaster, I'd consider the Containment Zone aspected towards violence and war, but not to religion or spiritual elements. However, I freely admit my Chicago knowledge is more from the Cliff Notes version of what happened than having played through all the game events of the past 20+ years.
