In one of their innumerous conflicts, they have entered the territory of a major population center of your choice. Their struggles have already destroyed several villages and now they threaten to trample the capitol in thier next skirmish. Both sides will ask the PCs party to aid them in defeating the other. The fate of the capitol city and innumerous lives are hanging in the balance. The PCs choice; whether to take sides, try and find a way to neutralize both, or just ignore it, could potentially save or ruin the nation and end or inflame a centuries-old conflict. Not to mention the moral dilema of which is the lesser of two evils.
Really good idea but I think this would work better as two rival families of dragons, both of which are evil.
