Tide Sanctuary.
"Uh... cough... Magic Power... thin..." Saphirea curled up on the coral bed, suppressing her voice.
The thin Magic Power around made Saphirea feel like she was having altitude sickness, her whole body was in a state of sustained discomfort.
In fact, as an Underground City, the Magic Power inside the Tide Sanctuary should be thicker than the normal Environmental Magic Power outside.
The reason Saphirea felt the Magic Power was thin was purely because the magic concentration in the Mist Illusion Realm was too abnormal.
Using magic intensively in the mist, with the body constantly washed by such high concentrations of magic, resulted in sensory imbalance and symptoms of magic addiction.
Luckily, the time trapped inside wasn't long, just mild magic addiction, with proper adjustment it can be adapted, though not without some suffering.
Outside the Tide Sanctuary, the sea had already been swallowed by the mist.
