There are plenty of ways to relieve the fatigue accumulated from many days of hard work and stress from various situations. Some would go to a local spa to relax and get treatments like massage and aromatherapy. Some would visit various places like the beach and do some vacation. While the majority would just go back home and have a good and long sleep that they needed the most.
Elaina is not a stranger to those things. Back when she was the empress of Luminiera Kingdom, she usually resorted to these methods to reduce the accumulation of the troubles that they were feeling in their bodies. But if there is no time and good reason to do any of these, she just decides to have a good and long sleep.
But these methods are not a surefire way to remove all the accumulated fatigue. They do reduce them to a certain degree, but they are not gone for good.
However...today, Elaina felt the bliss of something that she didn't think she would experience.
