Most of the containment zone has no specific aspect. It's more of a warp than anything else. It's been twisted by far too many elements for any one specific domain.
I have to say, I'm disappointed by this. It really leaves adepts in the cold when it comes to the penalties of background count, while magicians can use Clensing (pg 155 Street Grimoire) to reduce or even negate the penalty. 13+ dice (Counterspelling 6, Magic 6, Initiation 1+) against 2-4 dice of background count means the magician will on average reduce the count by 2 points even if the background count affects the cleansing test...and it can be done more than once.
Clensing is also a LOT cheaper. To get Domain of the Spiritual or Domain of the Warrior, you first have to get a 20-point Quality (which will cost you 40 points after character creation) followed by 13 Karma for initiation...all to reduce the penalty by 2. Yes, the adept has the option of spending an initiation on Adept Centering...but by the rules that only helps with Physical and Combat skills. That won't help initiative, or an adept that wants to do more than jump walls and beat on the bad guy (Social adepts, for example).
Any chance the nature of the multiple elements in the background count could be reflected by allowing a partial reduction from Domain of the Spiritual or Domain of the Warrior?
On a separate note, it seems like the book has a different take than Missions on how large a "neighborhood" is. You gave an
earlier answer about the home ground quality, saying that a neighborhood is just a few blocks in size. The example given on pg 32 of Street Grimoire infers that "the Barrens" would count as a neighborhood, and that's pretty huge (more than a square mile). Given that it's a 10 point quality that is effectively useless under the current interpretation (at least in a Missions game), would you be adverse to revisiting that ruling?
