Raiky , a battle mistress from an amazon like race located at a remote corner of the universe.

One day a metal bird appeared in the sky and burned the world as she knew it.
Her people captured in chains and forced to battle each other for survival.
She stood out from the rest of her people both in skill and beauty.
The son of her conquerors leader took a shining as she survived each day in the area and convinced his father to give her a boon.

Raiky would prove her skill against any and all who challenge her in the arena and if she survives she will be rewarded with ...life.
Days passed as she killed all her challengers and finally after 5 days of tiresome , unending and gruesome death she won.
For this feat the "emperor" granted her knowledge , a new enhanced body and a chance to serve beside him if she so chose.

2 days after Raiky won , she awoke in a nice bed , her mind full of information she didn't have before and a cybernetic arm made from a rare metallic alloy that never rusts or ages.
The son of the "emperor" , Tobias galivard the 4th , sitting next to her , explained what happened and why she came here.
Fueled by rage and desire for revenge against this beast who killed her people Raiky massacred all but 1 man in the hospital wing she woke at.
Tobias , spared for the chance he gave her many days ago.
Raiky using her newly acquired knowledge and power tore apart through the empire and killed the "emperor" , with his blood in her hands vowing to protect those in need.
