On the bright side, the Kalle system is 40 light years away from any other system, so they would have something like fifty years to prepare for the Tyranid invasion since they have no FTL. Given the insane adaptiveness my humans have shown in earlier RPs, I think Lakfakalle might just stand a chance.

Of course then there will probably be an extra-universal invasion of doom. Because we can't have anything good happening.
