How are Morgana and Stella related?

Maybe Stella's mother was a powerful witch who fought against Morgana too. And because of Morgana Stella lost her mother.

Or... Morgana is Stella's mother and she looks like skeleton because she's under a powerful curse.

My thoughts on this issue:

Morgana’s Origin

Part One

Stella stomped into her house, angry and frustrated.

"I am so tired of being mistaken for that other Stella! I mean, what's so special about her? I'm an excellent witch too!" Stella muttered, hugging her Cat Hieronymus the Mischievous.

For the thousandth time, Stella thought about changing her name. For a long time she had stubbornly refused to do that, after all, she had every right to that name. But lately, feeling worn down, she had been seriously considering it. But what name to pick? She looked around her living room, and a musty old Tome on her overloaded shelf caught her eye. She had brought this Book, The Legend of King Arthur, to the King Community from human world. In thisSaga, there was a dark Witch named Morgan le Fey. Hmm...

"What About Morgan?" She asked Hiro...

"Meow!" Hiro cried, lashing his tail.

"No, You're right, I don't like Morgan for a name either. But... I Love.. Morgana!"

Part Two

That fall, both Morgana and Stella attend the Institure of Higher Magic. After a rocky start, Stella Warmth and charm had finally won Morgana over, and they had become fast friends.

Stella was studying for her King Community Magic Academy Saga exams, when she heard a knock on her door. As she opened her door, as figure with a skeletal face jumped out at her, shouting “Boo!”

Stella Shrieked and leaped back, but then the figure laughed and lowered the mask, revealing Stella’s mischievous best friend Morgana.

“You gave me a fright!” Stella laughed, giving Morgana a Hug.

“Anyway, I’m glad you’re back, we need to study for our final exams,” Stella continued.

The two witches opened the spell book and prepared to work on their potion for the exam.

“How much Bitterroot do we need?” Morgana asked holding the jar up.

“Two pinches...” Stella started to say.

Morgana tossed in two whole roots.

“Wait!”, Stella threw out her hand

But it was two late, the excess Bitterroot caused the Potion to explode, splashing Morgana in the face, transforming her body and mind.

“Stella, you did this!” Morgana threw back her head and cackled madly, Pointing her wand, clutched in her bony fingers, she threw a bubble spell to trap Stella, then jumped on her broom and flew out Stella’s Window, trailing Black smoke.

Stella’s best friend had just become her worst enemy!
