This is something I'm thinking of running at Dragonmeet at the end of November, and possibly publishing as a small game supplement with two or three adventures and support material.

Basic idea is a "twenty years later" continuation of Too Many Dragons, one of the adventures from my Nesbit book, Fables and Frolics, possibly adding in some of the Dragon Player Character stuff from the Tooth and Claw setting. The first adventure was set in a Welsh village where a group of meddling kids tried to find a dragon before its eggs hatched and its children devastated the countryside. At the end of the adventure they usually end up helping the dragon deal with the real threat, a meddling dragon wizard who is trying to gain favour in the Dragon Emperor's court (in another dimension) by persuading the dragon to reunite with her husband, the Emperor. The kids aren't going to be a threat if she brings them up properly.

Flash forward say 25 years to 1940-ish. The baby dragons are now teenagers (hatching took a LONG time), and live and work among the humans in the same village (dragon magic includes shape changing). Mum is still around, of course (dragons are VERY tough and live for centuries) and now runs the village pub or something of the sort. But the war is causing a few problems:

• Meat is rationed, and dragons are obligate carnivores who need a sheep every two weeks or so, or equivalent. Each.
• They're coming up to conscription age and while their shape changing is good, it isn't perfect and probably won't fool the sort of medical you have to take to join the forces or be medically excused from service.
• There's now an important and very hush-hush military base in the area - RADAR, mining rare minerals for Britain's beginning nuclear weapons research, or something of the sort - and everyone is being warned to be on the look-out for suspicious activity, aircraft, strange lights, etc. etc.
• Probably other things I haven't thought of yet.

Although they're dragons, they're patriotic Brits and do want to do their bit for King and Country, and since they're not quite old enough to enlist they've joined the local branch of the Home Guard. Some of the older members are aware that they are dragons and will try to help, others are blissfully ignorant.

I think there would be a mixture of draconic and human player characters. Say two dragon "boys" and a "girl", Mum (probably an NPC), and two or three humans, at least one of whom starts off not knowing anything about dragons. Throw in the usual sort of Dad's Army problems, problems from dear old Dad (the Dragon Emperor) who wants his heirs well away from those horrible violent humans, and so forth.

Any thoughts? Plot ideas? And are there any games / settings I should bear in mind as covering similar ground?
