Why did Asha leave the order of love and light? We know she got burned out and depressed from the thankless, mind breakingly depressing work that is medicine but how did she get so bad that it caused her to leave and give up on her dreams? Did none of her sisters attempt to help Asha out of her slump? And why take back her old name and become the private physician of the Uekoro royal family specifically?
Most minervae have sworn loyalty to Karenza, the Divine of Love, and have set out into the world to make it a better place with their powers. They work tirelessly to do this, pouring literal blood, sweat, and tears into their efforts.
Dr. Asha was once a very prominent figure in Matuzu Kingdom, known then by her minervae name, Charity. She became famous during a horrific plague that ripped through the Midlands long ago, and her efforts to fight this plague likely saved the kingdom from collapse. Statues were built in her honor. Matuzans adored her. Soon she gained global notoriety and was summoned to all kinds of catastrophic events worldwide. She was summon to war zones, plagued cities, and polluted villages with poisoned residents.
It seemed the suffering was never-ending, and as soon as she cleaned up one area, two more would need her help. She would often visit the same locations over and over, disappointed that conditions had not improved and citizens were still falling ill or injured. She pleaded with leaders to help their people, to stop the wars and improve sanitation, but her pleas fell on deaf ears, for they preferred to continue their corrupt ways and summon her to clean up their messes instead.
Charity could see the writing on the wall. She was being used as a political pawn, a tool to make these leaders look like they were making an effort, but they had no intention of actually helping their people be well or helping her make the world a better place. She felt very alone in her cause, like she was pushing against an immovable force.
Then one day, without warning, Charity seemed to disappear. She was not responding to her summons and no one could find her. She was presumed dead until she resurfaced centuries later, operating under her old maenad name "Asha". By this point she had mostly fallen out of the public consciousness. She was remembered only as old statues that stood in front of a few hospitals, and their features had worn with time, no longer even resembling her.
Dr. Asha was tired of hiding away and doing nothing. She wanted to help allkind again, but she felt like a failure because she realized she could not save the entire world like Karenza wanted. She just didn't seem to have the strength and resilience her sisters had to keep up her efforts. Asha could have sought the support of her sisters, but she was too ashamed of her perceived failures and couldn't bear to face them.
So, she decided to return to her home city of Uekoro. She used to be a harem lady for the royal family, but ran away to become a minervae. The royal family accepted her back into their lives, this time not as a slave, but as their personal physician.
Dr. Asha hasn't set foot outside the Uekoran palace since. Some say she's hiding from the world, afraid that she will be summoned to an endless stream of catastrophe for all eternity. It's possible that she has lost hope in allkind, and she's afraid that if continues subjecting herself to its mass dysfunction, she may just lose hope too.
I think it's safe to say that she suffers from some level of depression. Burnout is common among minervae, but they usual counsel eachother through it. In Asha's case, she was too ashamed/stubborn to seek help.
She is the type of person who will break her back taking care of everyone around her, but can't lift a finger to take care of herself.
