Well, there were two incidents that started this recent bit of dragons making moves in the open. The first was the Artifacts Rush, when some artifacts from older ages of magic started 'waking up'. Four of the most powerful eventually ended up in Ghostwalker's hands (as he meant them to) and he used them to close the Watergate Rift and bring back Zebulon. The second event was Aztlan provoking Amazonia into war. Back a decade or so ago, during the Yucatan revolt, the Azzies sacrificed a dragon, autopsied the body, and put the corpse on display in a museum. This pissed the dragons around the world off something fierce. When Aztlan and Amazonia went to war, this gave Sirrurg (not known for being one of the more subtle dragons) the excuse he needed to run wild on Aztlan. Hestaby broke from the script by going to the UN and airing the dirty laundry. This set off a series of moves and countermoves and the more supremacist faction of the dragons decided to start hunting talismongers, dragonslayers, and the like, which of course sparked reprisals from metahumans. Alamaise, always glad to have an excuse to poke his brother in the eye, took the opportunity to declare GeMiTo his hunting grounds, and got a bunch of younger dragons to come to his side.
Which leads us to what happened in Storm Front.
For the most part, the dragons are still doing their plots within plots. Celedyr now has to balance his research projects at NeoNET with being Loremaster, Lofwyr still has SK, Ghostwalker still has Denver (and is likely going to burn the Azzies out of it), Ryumyo and Lung have their syndicates, and so on. The dragons have never exactly been idle, its just that a couple major things came to the surface, and people couldn't help but notice it. And you'll notice that when dragons move in the open, the world shakes.
The question, of course, is what Hestaby will do now that she is out of Dragon society.
