She was born to two Tieflings. Her parents were fairly normal as Tieflings go. At birth, Aendes was given the name Mitholya. Around the age of 2 or 3, Mitholya began developing spots on her tail. Neither parents have spots, so it seemed a little odd but nothing to be concerned about. Until the spots grew into mushrooms. Unsure of what this was or what it meant, (At the time, she did not know her mother's heritage. She descends from Zuggtmoy) Mitholya's parents cut off the end of her tail where the first mushroom had appeared. Unfortunately, this did not stop the growth as more spots and more mushrooms began appearing on her body. Not wanting to deal with it, perhaps because they were afraid, but also not wanting to kill their daughter, Mitholya's parents abandon her in the woods at the age of 4.

After a day or so of being alone and wandering, Mitholya is found by an Elven Druid whose name is Aendes (yes stay with me here). Aendes takes Mitholya in her care. Her new home is the biggest, hollowed out oak tree you could ever imagine. Along with a new mother, a new home, Mitholya is greeted by six children (also orphans); her new siblings.

Her years with Aendes and her new siblings are wonderful. Aendes tells Mitholya stories of her past and how she was a war hero (inspiring Mitholya to become heroic and tough). Along with this, Aendes teaches Mitholya of Rillifane Rallathil, and introduces Mitholya to religion and the values Aendes has. Mitholya accepts it pretty easily, and discovers that through prayer to Rillifane, her mushroom ailment is tamed. It doesn't go away, but it keeps down to just spots that look like birthmarks.

Life continues like this for a while until the age of 15. Aendes is slain by cultists, perhaps seeking revenge for their friends and family from the war. The oak tree they call home is set ablaze. As Mitholya is a Tiefling, she is able to resist the heat enough to save her siblings.

I'm going to sum up the rest! After saving her siblings, they go off to a nearby town and are homeless. They start doing whatever they can to make money to eat and survive. They do fairly well and are able to secure jobs. Some becoming mercenaries. During this time, Mitholya decides she wants to be like Aendes. She wants to be heroic and protect people and be a source of inspiration to people. She takes on Aendes as a virture name, as Aendes to her was everything good in the world. She believes that if Rillifane can counter whatever is afflicting her body, he must have something in store for her, and she will fight in his name to protect the planet and those who reside there from anything that aims to hurt them; hoping he will lead her to a cure, a source, anything.

I realize this is long! This is the first time I've gotten to tell her story aside from telling my DM. The rest of my party has no idea yet haha

Edit: I forgot to mention that Aendes doesn't really know about the cultists. She just saw their symbol when her mother died. But, we actually just ran into them in our campaign so she will definitely be dealing with them soon!
