At the suggestion of going along in Josef's barge, the high elf Aaryn seems to go into thought. He closes his spellbook and clasps his hands together, as he often does, to show that he is in deep contemplation. It does not take him long to weigh his options. Within a few moments, he looks up and says merely, "Yes."
Later, when Aaryn notices the group is being followed, he stops for a very brief moment, just long enough to form a thought, then whirls about quickly and decisively. With a mere wave of his hand he conjures up a ball of bright light before the follower and states loudly, "I dislike subterfuge. Reveal yourself!"
