Nailisi slept for one week straight. On the Myers mainland, a week had six days. These six days represented the six elements, set in a cycle. The Holy See tried to disseminate the concept in the code by changing a week to seven days. Most people on the mainland opposed it, hence only the Glorious Plains adopted such a practice.
Every day, the Pan's Turtle alchemical boat would travel for eighteen hours at a speed of forty miles an hour, and six hours at a speed of sixty miles an hour. Consequently, the ship traveled over one-thousand miles daily. Nailisi slept for six days, and by then, the Pan's Turtle alchemical boat had arrived at the periphery of the Frozen Sea.
