I agree that dragons are under-used, but I'm not sure how they are organized or operate. The only ones I know of are Ferrovax and Sirriothrax, the latter of which was killed by Michael Carpenter. I think a Dragon would just be plot-device powerful... a GM's Player-be-good-stick to club people over the head with. Then again, history (if you base it off myth, lore, and legend) is full of dragons being taken out by even every day mortals. Know-how is a big part of it, so maybe they aren't that big of a blunt object. 

 The Outsiders could certainly play into things. 

I agree that the White Council has its own corruption and problems, especially with Nemesis causing trouble there. I think in this particular scenario, as in present-day... it would put itself on the side to get rid of the ThreeEye again. There are better ways to amp up magical ability, without such hideous side-effects. 

ThreeEye is kind of cornered on the market, and is being watched for. How about... a new drug. ThreeEye behaves pretty specifically, in what it does. That's usually one of the things about magic in general. Perhaps something new hitting the streets would be better. Something that gives people a supernatural high, and then thus amps up their energies. Evidence for this is seen in Fool Moon when Harry makes himself a potion to amp up, or refresh himself, like a Mana potion or something. It works great, and helps him a lot, but at the same time he blew through his refreshed energy very quickly, and it altered his judgement. For the average person, having a ton of life and magic jammed into them would be such a great feeling they wouldn't know what to do with it, and the high would last for hours or even days, and they would be a shining beacon. of energy, and probably delicious to darker things out there. 

As Harry put it when talking to Bob, he wanted something like a good night's sleep in a bottle. It worked, really well... and it was almost like magical methamphetamine, with a very feel-good component. Another way to look at it is something like a magical energy shot, like 5 Hour Energy... only much more enhanced and longer-lasting. Focus, power, energy, will.. A lot of people could use it for a lot of things, good and bad, even without magical effects.

So, problem solved there. 

The Wardens would definitely want to get involved. While this potion could be used recreationally and in a positive way... given over to darker, baser emotions, someone amped up on this stuff could manifest abilities, knocking out electronics, even creating bursts of energy and the like. If they figured out how to conduct rituals while on this, they could do some really undisciplined things. So then they start using it all the time and start learning magic but in a corrupt, twisted, unbalanced sort of way. Much like how Victor Sells was picking it up. Things could spiral out of control with this stuff, and it's addicting as hell. But it could instill and awaken real ability in others, which creates a whole new bag of worms for the Wardens to deal with. What do you do when you find one who's been using the Rise, and has the gift? That's probably going to depend on how, why, and what they've been using it for and with. It's going to require trials, much like when dealing with Lawbreakers. 

This also means that the Wardens might get new fuel, and the ranks of the magical community swell again. 

And if you want to be evil, perhaps a little seed of Nemesis could be carried in the potion. (I don't really like that idea, but it's a particularly evil idea that could be used. Maybe some of the potions have it, some dont, so there's a percentage chance of catching it...)

Just my unfinished/unpolished thoughts.
