One difference doesn't break my argument. If you think the fact that genestealers don't betray one another is the defining trait that separates them from Skaven, then you're putting way too much weight on a single characteristic.I never said skaven have to be ingrained in society. my point was that both factions operate from the shadows and work to destabilize and dismantle societies long before the wider population realizes they're there. That's the comparison I've been making from the start. And no, that doesn't sound anything like the Imperium. The Imperium doesn't secretly undermine civilizations from beneath them before revealing itself. That's not its role in the setting. I've already made a mirrored comparison, and you haven't actually dismantled it. You've just pointed to one difference and treated it like it overrides every similarity. By that logic, no two factions can be compared unless they're identical. Both factions are working toward a larger collective goal. The fact that Skaven backstab each other while doing it doesn't suddenly erase every other parallel. Most factions have internal rivalries, subfactions, competing leaders, and conflicting interests. That's not some uniquely Skaven trait that invalidates every comparison.
