Original Description:
 
I felt a wave of motivation to go back to the luna bath works I did a bit ago and decided to rework them and add some new ones. Plus, you know me, a story to boot! It’s broken up into four parts, so be sure to check out each one!
 
Part I/IV
 
After an exhaustive evening watching over the kingdom of dreams, Princess Luna retired as Celestia regained her scheduled control. She is flanked on either side by her most loyal guards until she arrived at her bed-chamber.
 
“Dear guards,” the princes speaks wearily, “We shall retire alone tonight. You are excused; we are very pleased with your performance.”
 
Not showing their sheer joy of an early night home, the guards trot away, leaving Luna alone. She enters the room, going straight past her bed and into the adjoining bathroom. She approaches her large old tub and immediately starts the water. While the bath is running, she lights the candles on either end of the bath and looks out her grand window at the sunrise. These candles were gifts from a local candle shop, newly developed and enchanted not to melt.
 
Once the tub reaches about half-full, Luna adds her favorite oils and solutions into the water; all her favorite scent: lavender. The water begins to turn a shade of light purple as bubbles begin to expand. It isn’t long before her bath is full, and the water is stopped. She eases into the cast iron basin, feeling the immense heat surround her. She sighs, lifting her forehoof covered in foam, and playfully blows them across the room.
 
“What a nice soak,” she whispers as she sinks deeper in bliss…
