There was a legion stationed outside the village now, closer to ringing it in a blockade than anything else. Or so Naironi put it at least. Every time she had to pass through their checkpoints on her way to pick up supplies from the countryside she felt nervous. These men had dark strains to them. She could see ruthless tendencies in their eyes and wondered how they could be here to protect them and not to conquer. Who checked their authority, she had to ask. If they chose to rape and pillage would anyone stop them?
There were pirates now. They raided everywhere up and down the coast, but they had hit the village twice now in succession so the King sent troops in case they tried for a third time in a row. There had never been pirates before, not in her lifetime or that of her parents and grandparents. This was something new and entirely unexpected and the village had been caught by surprise each time. No one knew just where the brigands had come from, just that they were here now and posed a danger.
The topic doesn't shift too much, but the attitude does. You could successfully combine her fear of the soliders and her fear of the pirates, but instead they come across as entirely separate ideas, like there are two characters thinking about the matter from different points of view.
