Looks like a good start, but I always like a little info about the world and maybe the recent history before getting to the beginning of the current story. Tho thats just me and such details might not be relevant to your story.
On a dark night.....
A nightmare came true.....
One village completely destroyed.....
And only one survivor.....
Who seems guilty of it all.....
Mom: Seara! Seara run!!!!!!!
Seara: Sis!! What happened to her?
Mom: No time, you need to run! Quick!
Seara: What's going on!
Seara: What is this nightmare?
Seara ran.... she ran as fast as she could to get away from what she had witnessed.
Without understanding what was going on...
She ran as fast as she could....
She was running in such a panic that she didn't even see who or what had hit her.......
What had happened?
Up to you but see if you like any of the changes I've put in the below. Borrow, ignore or feel inspired at will.
On a moonless night, so dark that even the brightest stars failed to shine through...
A terrible nightmare came true.
An entire village, completely destroyed by the horror...
Would be survived by only one soul.
One soul, who escaped the terror...
One soul, who seems guilty of it all...
Mother: Seara! Seara run!
Seara: Sis! Wha... What happened to her?
Mother: There's no time, you need to run now!
Seara: Mom please no! This nightmare! Whats going on?
Mother: RUN!
Seara ran... she ran without turning back to see the horror that her ears witnessed...
Without understanding what nightmare consumed her home...
...and her family.
Seara ran with a fevor until a strike from an unseen assailant ended her dash...
and her terrified mind slipped into the calming darkness of sleep.
