I would assume this isn't the case as that would be broken but, Since the hive mind we are getting is a centralised organism and all the pop's are just extensions of it's self, does that mean that if the hivemind homeworld is captured the entire species would die out as currently hivemind pops die in non hive mind governement and non hivemind pops are killed in hiveminds.
This would mean that technically when the hiveminds homeworld is captured and the hivemind core is destroyed that all the drones would die as the entity that was sustaining the hivemind would be dead?
By this logic hivemind planet's cannot be liberated. Also hivemind presumably cannot invade primitive worlds unless they also move pops there.
The hive is distributed across all the pops evenly. Wiping out the homeworld would deprive it of many billions of drones, but the driving sentience would survive in the rest.
It's not like Ender's Game where killing the Queen wipes out the whole hive. It's like the Borg, where defeating a million cubes does virtually nothing to the Collective's intelligence because there are literally trillions more out there.
