So, what is the Cerulean Horde you ask?
I'll give you the backstory from Thom.
For those of you immersed in the fluff of the second edition, you're well aware of the Elves campaign of destruction against the dragons of Chronopia, including the stealing of their young to utilize as their Dragonbane mounts.
Well they missed one.
A few survivors of the Dragon Clan Dwarven massacre have sought him out, as this last dragon has been under the sea for the last hundreds of (thousand?) years "genetically engineering" sealife. When he learns of the fate of the dragons and the Dragon Clan Dwarves, he's ****ed. I mean ****ed. So he sets loose the Cerulean Horde against the Elves, and the Vulture Clan. The idea is very focused; if you want to come between their enemies and the Horde, you're fair game as well.
The Dragon Clan was wiped out for the most part, but part of the Horde may consist of "infiltrators" that have joined the other clans. This would mean gamewise that you could have some legion troops from the other Dwarf clans to go with the horde. The Dragon Clan Gunners are not armed with blackpowder; their guns are more like bioweapons than firearms. The Cerulean Mists comes from the blue mists that come off of the magic that the Horde employs against their enemies.
That's all for now.
