In Lindworm where monsters and humans live together peacefully, a human doctor named Glenn who specializes in monster medicine runs a clinic with his assistant Sapphee. They see numerous patients on a day-to-day basis. One day, the arena in town asks the clinic to do physicals on their fighters and they happen to meet a centaur girl named Tisalia, who is basically centaur royalty. She is an excellent fighter but seems to be on a losing streak lately. Her attendants, Kay and Lorna, are worried that Tisalia might be suffering from some kind of ailment and ask Glenn to examine her.
Probably due to the fact that she exercises 
regularly and practices temperance.
