Dragons of Post-Apocalyptic Twilight

I guess this is the third in a loose series of re-imaginings of old TSR settings. My knowledge of classic Dragonlance is admittedly a bit limited, but what I don't know about it, I figure I'll just fill in with other post-apocalyptic, science fantasy, or sword and sorcery stuff.

So, Kyrnn is a world locked in a protracted semi-Cold War. One side or the other (perhaps both), looking to end the stalemate once and for all uses their advanced science or scientific sorcery to pierce a veil that should have remained unpierced and contact another universe where an unlimited source of power was waiting. That power had an intelligence. They called it Tiamat.

Tiamat agreed to help their cause and taught them how to make living weapons they called dragons from a portion of "her" own substance. Their early victories were great, and several enemy cities fell before the dragons, but then somehow, the opposing side got dragons of their own.

When the two blocs were utterly dependent on dragons, the beasts turned on their masters. Civilization was nearly destroyed in the onslaught.

The only good Draconian...

Centuries later and Krynn is a world dominated by the dragons, and their lackeys the Draconians. The former dominate species now either fear and avoid or serve the planet's current rulers (not unlike the humans in Vance's Planet of Adventure, or maybe even the Planet of the Apes TV show).

Anyway, the idea is to make it more random Sword & Sorcery 70s paperback than Lord of the Ring.

Goldmoon?
