I want to start a discussion about Deneb sector. Who better to start with than Mike West, whose done boatloads of quality work on the Regency and its heirs (oh yeah, plus a little bit of stuff on the Darrians
Quite so. For reference, here's a tiny map of Deneb.
Of course, http://travellermap.com is the preferred browser...
0406 is Pretoria, subsector capital.
0316 is Magash, an Important world.
0629 is Askigaak. Note that it's not on the Xboat route...
1122 is Vincennes.
1925 is Deneb.
Implications:

While working on another project I have to admit that Deneb was a difficult subject. I was fortunate in that I had it pre-blown up. But, there are still several things, even in the CT era, that seem ripe for exploration.
First, have you actually looked at the world government of Deneb!? Or its star? Despite being the "sector capital", the world has a ridiculously repressive government and is very, very hard to get to because its star's 100D limit is so insane. That world alone should be a cauldron of political intrigue (if not an outright basket case). Its interaction with its neighbors, and the Imperium itself, is guaranteed to be nasty at best.
You have the entire Vargr frontier. You have a couple of worlds that have outright corsair bases in Deneb (something even the Spinward Marches does not have). If you like Vargr-related shenanigans, the coreward border of Deneb puts the comparatively tame Spinward Marches border to shame!
Of course, you have Vincennes. It is a TL 15/16 world that pretty much does its own thing. What does that mean? It is a technological powerhouse that has no equal in the entire Domain. Why is it not the capital? Did then get outmanuevered? Did they not want it? Just because Deneb is the sector capital doesn't mean it always has been. (And just because we know Mora better, doesn't mean that it is yet ascendant. Mora does not truly ascend until Norris moves there in MT/GT. Until then Mora is simply the nominal capital of the Spinward Marches, not the Domain of Deneb.)
And, my personal favorite, Askigaak. It is a dinky world with a very thin (tainted) atmosphere, TL C, E starport, with 90 billion inhabitants. WTF!? What is it doing? What is going on? How do they not kill each other? Why do they only (officially, anyway) have an E starport? Askigaak should drive enough trade to control the entire sector. Does it?
So, Deneb is not quite a placid as it would seem in the first glance.

Implications:
- Check out Deneb, the world. I see four red-zoned worlds very close by. Something's up.
- The coreward subsectors of Deneb are a mess, and one might be able to pin the blame, indirectly, on the Imperium Herself, or at least her proxies. Politics for sure. Ever had to bargain with a lawless system?
- What is the deal with isolated, high tech worlds like Vincennes? The Imperium can't or won't assimilate them and their technology. Sounds like a huge SNAFU, wrapped in an enigma, shrouded by Red Tape.
- We don't know squat about Deneb's history, nor when Deneb became the capital of Deneb... funny that: if the capital were elsewhere, then what was the sector's name? Something Vilani, perhaps, but maybe not. Anyhow, that means Deneb (the world) was pretentious enough to rename an entire sector when the capital moved? Just makes them sound more evil than ever.
- Askigaak should drive enough trade to control the entire sector. With an E starport, it doesn't. Then what is going on? Soylent green? "Re-education" World for Deneb Dissidents? No, too pat. But I see what you mean, there are mysteries to probe here -- and they're all political, by the way.
