Fang island is quite far from the barrier. It's so far out there, it could not be seen at all.
As the winter is approaching, the sea is full of fog.
Sasha set off to search for Fang island amidst the fog.
She has a feeling that she might get lost, but she had a premonition Rudy might be alive.
Like everyone else in their family, the day of his trial is also approaching, and if she doesn't go, Rudy might not make it out alive.
So, even if she could not tell east from west, even if she could not even see Moon snow's head sitting on his back, she must go.
Thus, she did and gave directions to Moonsnow following a compass in her hands.
It's a curio obtained from Espana, and is said to be used by only warships of Espana.
However, within the Smoking Winter sea, the compass behaves very weirdly, so it's not used for this leg of the journey.
Sasha decided to use it for as long as she could.
After all, no matter which way she goes, she is setting out blindly.
