S-K's North American HQ is a bit of a bugbear.
It's mentioned as being in Charlotte in a place or two, but in the Tir later, which made more sense since, you know, he was on the Council of Princes and had to be there from time to time for official duties *anyway*. For Dirty Tricks, this got a bit of a massage, with the Charlotte office being the CAS HQ that was large enough to serve as the NA HQ, and was being set-up as such during the Dragon Civil War, until Hestaby got defanged in the Tir herself.
S-K Prime got a North American HQ in Atlanta, and S-K as a whole is quite popular in the CAS, allowing them to fan out from there.
Since the NA HQ is in Portland, just down the river, it makes sense that S-K wouldn't waste a ton of money building up officies in Seattle, but it's safe to say that they have lots of subsidiaries skulking around in disguise.
