An Extra Character Became A Villainess

Hello, I'm the author of this story that I started two years ago. It's been a while, hasn't it? Today, let me clarify a few details about my character, Selentia, who was introduced in Chapter 1. She mentioned that her family was tragically murdered two years prior by unknown assailants. I understand this caused some confusion about her age in subsequent chapters and the abrupt shift in the plot. I sincerely apologize for any confusion caused by this oversight.

Allow me to provide more context now.

Firstly, when her parents were murdered two years ago and she was just 8 years old, she now states she's already 10 years old as she explains her story. In these messages, it's clear she harbors a strong desire for revenge against whoever was responsible.

"I've always yearned for vengeance as I grew older, honing my skills in swordsmanship and magic, blessed with abundant mana within me. My mission is to survive and eliminate the many traitors of the Lavastian Empire.

There are numerous traitors—those involved in illegal drug trade, many who have leaked the empire's secrets, or even those who conspire with our enemies to bring about the empire's downfall."

and here when she says '9 years old she explains that a year ago she found out she had a lot of mana than she thought.

"When I was 9 years old, I discovered that my small body was infused with a mysterious and incredibly rare magic. Amazed by its power, I decided to keep it hidden and diligently master it as I grew older." (she's already 10 when she explain this.)

Later, in the last Chapter 1, when ellen says 'after four years of living with my new family, in that part she's already 14 years old.

SO MANY TIME FLIES BY HUH? DONT WORRY I HAVE A GOOD EXPLAINATION FOR THAT SOON. ITS STILL A SECRET.

After I finish explaining her ages over the course of the 7 chapters, more details will gradually unfold, so there's no need to worry.

Now, let me provide further context:

"Four years have passed—it feels like time has flown by, yet here I am, still feeling like a child. But none of that matters now. This is my chance to hunt down those who took away my loved ones."

With the first sentence, several more years have passed. She's now 18, an adult. It might be a bit confusing, but the character herself will explain everything soon, dear readers. Are you curious about what has happened to her? About her quest for revenge? How she trains and more? Don't worry, Ellen will tell you everything.
