Deciding to dust off this thread, need to keep up with this. Mostly a brainstorming post this one.
So been trying to decide the last of the 4 Seraphon armies, how the fluff is linked between these.
The Swamp lizards (still needs a name!) being one of the main good groups, but due to the events of The End Times they are stuck in the stars, how most rely on a Slann and their one went off somewhere, Ataxa is the only one left alive and is forever roaming the realms in search of artefacts in hopes it would return the rest of his kind to him, or hopefully finding the missing Slann.
The Coa'Xoach are another set of good guys, they spent most of the time roaming the more lush jungles of Lustria. They are known to be cunning deceivers mostly due using their bright, pretty colours to fool, somehow it worked most of the time. In AoS they was able to protect their spawning pools and are found hidden deep away in magical vegetation in the realm of Ghyran, they are seen sometimes working with the Sylvaneth whenever Nurgle decides to creep that bit too close to their territory.
The Chaq'Kai can be seen as bad in the eyes of the other Lizards, in the Old World they were known as a forgotten spawn of Lizard, hiding away in a sunken temple. Following their own god and would often bring sacrifices in hopes to bring him forth, this also included other Lizardmen at the time. In AoS they still have the same blood frenzy mindset, they developed the idea to ally with others but only to scavenge whoever falls in battle. They also was able to bring their god to the realms but it doesn't stop them for continually sacrificing to make him stronger.
Then there is the last one, haven't worked out fluff at all yet and their purpose. Being that I am converting the Saurus Centaurs and the possible Carnosaur version I might do something around them. Makes me think something went wrong somewhere and the riders fused with their mounts

Possible chances they will be another bad guy army, keeps it even then. Always have some old ideas that I can revisit.
This would also mean coming up with colour schemes and everything.
