Granberry and the other more proactive strong monsters would be quite the problem. If we go by in-game encounters then her at illiasburg would probably stop the entire plan. Most reasonable solution would be to go around, same thing with mary sue knight, would need to sneak over to the main land without attracting her attention.
But if we're going according to this scenario I'm sure some of the less suicidal monster fucking anons would have both of them completely distracted.
I have no doubt we could get some of the locals to join in, but even more bodies wouldn't really help until we get real equipment.
And no, (true) surrender is not an acceptable answer, it's either dying now; fighting for a chance of a free future, or eventually going extinct by monster fucking.
Then again, if this would be a real scenario we'd probably die early, unless we can bait ilias into spamming mass resurrection and time fuckery, then we got an actual chance.
