After reading Grant's letter quickly, Amber frowned as she read about the North Sea, that fellow's experience, and his strange suspicions.
Grant had obviously 'taken it easy' with his theories about beings plotting in the North Sea of the Spiritual World.
In the time he had lived in Dry City, he relearned how to socialize again. Also, he realized how his words could sound like those of a madman if said or written with the emotion he had when talking about the subject.
So he had learned more 'restrained' ways to avoid worrying reactions to his fantastic theories.
His letter had been written that way, but still, the topic covered was not simple, and Princess Quinn could not help but narrow her eyes and look strangely at those sheets of paper.
