Like many entries, this began as a simple hack. I picked up the Council of Wyrms boxed set at a local used bookstore. TSR pumped out a lot of great settings and content that's ripe for a Fate conversion. The boxed set is full of a lot of great ideas, and it is especially interesting to see a game that tries to recast the popularity of Vampire's "PCs scheming vs. PCs" in terms a different audience can understand.
Playing dragons as PCs is a no brainer. The elapsed time from the moment someone first said "Wow, I can't believe we killed that thing!" to "Hey, how come I can't play that thing?" was likely less than two seconds. I ran a fairly lengthy game of FFG's Fireborn and coming up with challenges for such powerful characters was part of the fun. The trick is to properly convey the scope of the PC's power, while still coming up for interesting things to do. the Council offers a great setting that mixes intrigues in the halls of power and heading out to the islands to lay waste to some armies.
This is still primarily a hack for Council of Wyrms, though you can get away with playing this setting without needing the boxed set. You'd have to make up your own fantasy world for your PCs to lord over, but that doesn't seem too hard. Either you've got a couple soaking up a few spiral notebooks (I know I do) or you can generate one using Fate Core's setting creation guidelines.
Consider this a gift to all the people who made Fate Core a two-fisted success this year and all the fan that said such nice things about Camelot Trigger. The rules for Parliament of Dragons begin after the jump!
This hack works for Council of Wyrms, Fireborn or any setting where the PCs are masters of their domain.
