It's late 1940 and world war 2 is in full swing. The Germans are ravishing Europe with the blitzkrieg through Europe, the RAF is trying to combat the German Messerschmitt BF 109s and Junker JU 87s ( Stuka), with their Hawker Hurricanes and Supermarine Spitfire MK.1 and MK.2, but both sides have been working on a thing that could change this war, and all wars to come.

In the secret labs of the Germans and English development on portals has become almost an obsession to all those involved. And finally, the day has come and the English are ready to fire up the first portal that would enable both countries to drop bombs on each other from thousands of km away.

On that day the king himself comes down to the lab to pull the lever that would power on the portals and change the face of war forever. However something was wrong, instead of opening a small portal, a huge portal opens in the sky above London. And out of those portals fly Dragons.

....

It's been 2 years since the first portal opened and now dragons have become a prominent part of life, even for the regular pedestrians seeing a dragon walking about has become almost natural. But where the dragons have become most important is in the military.
