Assuming that the ties between the homeworlds and the IS are cut after the WoR, there shouldn't be much information about the events we all know in the IS. So at least the official version.
I can't believe the Adders will not have one or two ways to get in touch, so that they at least know the bullet lines of the news. But it is hard to believe they have any real insight on whats going on and why.
What do the Star Adders want?
Being a dominant and independent force to be reckoned with.
Never bent the knees before Alaric and the Wolves.
Being the one who defines what it means to be Clan.
Sure they want to be the force that defines the way of clans. But WHAT is the way of clans? Surely not the kind of wrong decisions that led to the invasion and up to the WoR. From the creation of the clans there was just one dream to resurrect the SL.
This culminated in 3048 when the Outbound Light arrived in the homeworlds and up to the end of WoR in 3075.
After all the time this dream has crashed. There can't be any hope for a renewed SL in the IS. All the reason for their existence lay shattered before them. But what now?
The last arguments here tend to exile the clans from the IS. This is in hard contrast to the last philosophies we know from official sources at the end of WoR. Both philosophies, Bastions and Aggressors, are defined with the goal to go back to the IS.
But with time passing is this still their dream? Or do they find a new reason to exist far from the IS? It seems a bit weird just to define the own existence by being independent from tainted people. For what better ideal? There must be a better idea than Bastions or Aggressors have to go a new way.
And as this is still a game of combat there must be some kind of fighting. So if not fighting the IS, there must be a threat from unknown realms. Maybe this would open a whole new style of combat and enemies to the line of BT games?
But as the majority of BT fans don't want to have aliens, the only conflicts remaining are new inner homeworld wars or a new invasion...
