Lords of Winter will end in the formation of The Allied Federation of SpeciesThe Suul'ka will force the other species to form The Alliance and they'll politically merge.
The Suul'ka will winAnd the expansion will reduce the playable factions to the Suul'ka Empire and La Résistance.
Lords of Winter will have an actual campaign modeJossed thus far.
The Liir will commit mass suicide once the Suul'ka have been exterminatedThey sterilized gods know how many worlds in their quest for revenge and this is a species who considers anyone willing to take a sapient life to be incurably insane.
Possible future races
The Suul'Ka made the same deal as the Trolls.The Liir had attempted a session of Sburb once, but failed. Echidna made them the Bargain. Scratch took charge of the developement of Muur, and set about influencing the scratched versions of these Liir, now elders. They and a number of others took to space and became the Suul'ka, dominating and oppressing their childeren. As we all know, the Liir rose up and slew all but 7 of the Suul'ka. Not incidentally, these seven were members of the original eight that made the bargain with Echidna. The agent of this slaughter? The Black, future Elder of the Black Swimmers and number eight of the original party. He, much like the Sufferer remembered his original life and went up to space to confront his former friends, slaying their acolytes and scattering them to the black wastes of space. Scratch furfilled his end of the bargain. The Liir were now ready to attempt another session. The ectobiological relatives of the Suul'ka landed in the Worldsea by meteor at some later date. Scratch gave the Liir 8 pets. He didn't care what they did with them, except that they learned from them.
The Liir/a Liir faction intends to take action to prevent Suul'ka recurrence once the remaining Suul'ka have been destroyedThe Liir abhors the Suul'ka. So long as Liir elders can grow indefinetly up to hitting the square/cube-law problem, new Suul'ka can emerge from the Liir population. So, how to stop it? Well, the problem is that Liir don't die a natural death - and what are Liir masters of if not bio-engineering? If Liir elders can be made to die before they reach the 'can enslave the entire species' point, true Suul'ka would not emerge - so it just had to be made sure that not merely social standards keeps that from happening...
Stutterwarp works by folding spaceIt's the only FTL method with no fictional physics explanation of how it works. Human and Zuul ships travel along gravitational currents through fractures in node-space, Tarka and Hivers use the "Menisceal principle", and Morrigi manipulate Artificial Gravity, but there is no explanation how Liir ships teleport microscopic distances millions of times a second, it's just stated that they need an inertialless drive because of all the water aboard their ships. Now in Lords of Winter it is revealed that the Suul'ka can use psi to fold space and teleport great distances, what if the Liir attempted to duplicate this ability but couldn't find any non-Suul'ka with that sort of power and their machines could only fold space over minute distances.
The next expansion will not introduce a new raceInstead, it will add other new features, perhaps diversifying the current races. The intro will be narrated by a Tarka, Hiver, or Liir - or perhaps more than one.
