How about Pendragon? Could that have been Rhonabwy? It would go a long way to explain how he wasn't killed during his exploits.
personally I really do not think so. I think the Pendragon plot line, as well as the the New Druidic Movement stuff (probably have wrong name) were just story plots of previous writers whom were starting with the first layers of writing for the Shadowrun universe and attempting to first start attracting players using standard material starters to do so. But this is mine own opinion really, and I openly declare such.
Bigger conspiracies to me are stuff that I now (admittedly) have a more directly vested interest in. The Black Lodge being an appendant body of the Freemasons for instance (Conspiracy Theories), and knowing what I do of historical information regarding the Freemasons, the Templars, the Sylvestrines, etc.... That's a much bigger conspiracy with real,world inspiration and content to draw upon. And since the writers chose to have Roselyn Chapel be the target of retribution by the dragons after that fallout attempt on Lofwyr and Alamais in GEMITO, I'd say the dragons just started a war with a 10-million plus level person organization. Hence the reason in the games we have here, that War was headed off shortly after the declaration.

Aztlaners Kicking Ass and Taking Names. With the death (?) of Sirrurg and the acquisition of the bio-alchemical weapon Blue-227 (?), and the inclusion of those two super-spirits, I'd also say that Aztlan is once more fully vested into North America and the Treaty City. They managed to,win the PR war with Horizon. Win the War against Amazonia. Bring down Sirrurg. And return to Denver all in a very short span of time. The Big-A is well on its way back, if not already back and showing they are not afraid of starting extremely lethal,conflicts any longer.
From outr perspective, it goes something like this..... If the Great Dragons are going to measure at least part of their hordes in metahuman currencies, shares, and economic structures, then they are gong to be forced to at least partially succumb to the laws of the Modern Metahuman world. Hestaby tried to warn them. Before her, Dunkelzahn tried to lead them. With both of them now out of the dragon socio-political picture, it's going to be up to Celedyr to help them find a navigable, survivable future,for their species. And they cannot go on massive rampages, because the metahumans will fight back and they now possess the where-with all to do it. And the Allies. It's a game of Scorched Earth Retaliation. Only thing left would bethe Roaches ... And n Shadowrun, that's saying something special.
If however the Great Dragons denounce the forms of measurement of Metahumanity as part do their hordes, then they set themselves so completely apart as to render them all anathema . This would mean open season on not just Greats, but the non-Greats, Drakes, and Dracomorpha of all kinds.
My opinion, because a game without metahumans isn't a Shadowrun game, the writers (and thus the world) will not pursue any of the Great Dragon meta-arcs for a while. Perri and Hestaby are likely to be the largest possible exceptions IMO, and it just won't be the same.
Besides, dragon-based meta-arcs require characters that are normally ore experienced, and Shadowrun has now kicked off Version 5. Going to take,some time to build back up for many, if not most groups.
