My first thought on reading this thread was:
Now they've tipped their hand to the real Ancient Evil Dragon that they're likely to kill him, and he's mad. It may take them months to figure out who the evil mastermind whose minions are dogging their every plan is, and it'll make for a great "reveal" moment when they see this dragon, (apparently) back from the dead, aroused and ready to fight rather than sound asleep in its lair.
...
But, more sage advice might be, Epic-level PC's require truly epic challenges, and its fairly rare that a straight 'hack and slash' challenge can meet that. Its a very tough 'crux' moment for a DM to overcome, especially one who has typically met their increasing powers by providing opponents of similarly increased powers.
To continue to challenge them, you need to explore other threads. So, you guys have mastered combat? How good are you at running a kingdom? How good are you at political intrigue? How good are you at outwitting a foe? How do you defeat an 'evil' foe who is operating entirely within the laws of the land, but to an 'evil' end - yet, the law protects him, and it cannot be considered 'lawful' and 'good' to defeat him by force of arms? What do you do when some outside force threatens a pillar of your world: the arcane, access to the divine, etc.
Its one of the reason's I enjoy reading piratecat's story hour: he is very good at working through 'What happens when the group reaches insane levels of power?'
In essence, you want to look at their highest powers, and say 'What quest can I create which cannot be defeated by clever combination of these?' The answers to that will probably not be combat-based, and that's a very difficult shift of gears for the campaign, for the DM and the players.
And whose to say the dragon they just killed off so easily wasn't similarly illusionary?The more effective of the two tricks was a simple illusion.
