So many living things would be harmed. The fire would scorch the earth and take away food that a lot of animals around here depend on or it could harm the animals themselves. The unnatural fire could heat up the river and kill the fish and vegetation living in it. What would there be left for Nam to guard, then? What would there be for him to watch over and protect? Of course everything would likely heal in time, but that wouldn't erase Nam's failings. It would help no one in the meantime and it would lose him the river's trust. He doesn't want any of that.

He will make sure to contain the bird's fire. He will make sure that no sparks escape him. He will make sure that everyone and everything comes out of this unscathed.

"Thank me by leaving here as soon as you're able."
