The other possessed shumis.

The reason monsters went into Winhill was cause there was no men to protect it, I believe Raine said that herself. THAT is proof. Laguna then patrols the town and rids the town of the nuisances, after that no more monsters. Simple as that.

Of course there will be monsters in Esthar! A freakin moon "Tear" full of monsters landed right next to it! The monsters do this pariodically, no one is controlling it ( no, not Odine or Hyne ). I believe the Tutorial explains this clearly...

So there is some solid in-game proof for ya. Someone besides FE tell me if I'm wrong...

THANK YOU! that is what i was about to reply but u beat me to it and i thnk u.

So why weren´t monsters going into Balamb also?
I never heard of Balamb soldiers.
Or into shumi village?
And there were soldiers on Esthar.

Now,will monsters think:
Hey,this city is well protected so let´s not raid it?
Animals don´t do this on our world.

Also,the village is still unprotected on third disc isn´t it?

So much evidence against in one thread.

On the other hand monsters were helping Odine to get a hold of Ellone along with the Esthar dudes.
They also try to help Adel on her way to the palace on third disc.

That´s evidence.

one, balamb garden was right next to balamb so they could very easily take monsters out if they entered the city and wouldn't it be kind of obvious that they would've set up guards at the entrance to preent a monster attack? with shumi village, i don't think monsters can open elevator doors. with esthar, have u forgotten about the lunar cry? tons of monsters raining down right next to esthar? of course they are going to get into esthar! we have already proven that the monsters were not working for Odine and were not helping him to capture ellone. he had esthar soldiers for that!
