Okay... I guess what misled me is that you said "the TP." The Typhon Pact is the astropolitical entity that's depicted within the books. The label/brand is simply Typhon Pact.
One thing you wrote, Christopher, did catch my eye and I was wondering what you meant:
And by the same token, it's too early to say it's the end of that arc, since we don't know yet whether Brinkmanship will be a separate thing or a direct continuation of the same threads, and we don't know whether future works will do a similar kind of retroactive arc creation/consolidation.
What threads do you feel require continuation or are left "hanging" post-RtD?
