Turning right, then left, through the bushes and between those trees, Eisen steered Fafnir in the direction that the arrow created by Bree was pointing. Like this, they were finally able to proceed forward, getting further toward the forest's middle. The further they went, the more complex the forest's barrier became and the harder it actually was to navigate, but through the map that was created beforehand, Eisen was confident that they were able to get through without needing to be concerned.
And then, once the forest got so dark that Eisen wasn't even able to see the light from his own flames anymore, they pushed through. It wasn't even that bright out here; it was dim and foggy, like a particularly cloudy and moody autumn morning. But when you compared that to the absolute, unnatural lack of light in the forest thus far, even this gloomy environment was blinding.
