Heyo!
Astha's backstory:

Astha was adopted by a Druid village just a few days after her birth, the bastard daughter of a king, who as soon as she was born, banished mother and daughter from the kingdom.
Only Astha was found in a forest near the village.

Astha learned to live with nature and animals, lived a light life and learned all Druid customs and deeds, at least until she was 16 years old.

The kingdom discovered that Astha lived among the druids close to the kingdom and at the request of the queen, in a fit of anger at learning that her husband had a bastard daughter, ordered them to eliminate everyone who could spread the information. Astha managed to escape in time, but not everyone was as lucky. Some of the few who survived didn't even want to be near her anymore for fear of the consequences.

Astha for the last 10 years has been training and trying to be accepted in the world, which she knows has always been difficult because of her appearance, no one other than her brothers knew how good a person she was.
She seeks to find more Druid villages, and secretly take revenge on the kingdom that ended everything, which the Druids would naturally be against.

Since what happened, Astha has been having tantrums and her infernal side becomes more acute, she ends up not sleeping well and becoming suspicious of everyone.
