Dreams of Dragons: a nonextant board game

Last night I dreamed about playing a board game that, as far as I know, does not exist, but seemed pretty neat. It was sort of a sci-fi/fantasy hybrid strategy game depicting a war between factions of dragons on some other planet, with each player controlling one faction. I think each faction had its own unique elemental magic powers, but I don't recall the specifics. The game board was split into four hexagonal grid maps, each representing a different region of the planet surface, and players placed extremely detailed little plastic castles to represent their strongholds. The dragon warriors all started in an off-board orbital space station/palace controlled by the dragon royal family, and then teleported down to the planet surface to fight.
