Morgana Centurion.

Valerian was unaware that a storm has been let lose and it was heading towards the Lumen Empire with a speed that would change his life completely. Morgana Centurion had never failed in any task that was given to her. She was the secret weapon held by Jamal, the emperor of the Centaur nation. 

Fragrantia had moved back to the Lumen Empire safely and the crown of Stella Nation rested on the head of the young Duke, Lux Constel. They achieved their goal and what they needed now was to wait for the opponent. 

...

One day had passed, and Fragrantia was sitting in her study, looking at the various reports submitted by the people, when a shadow appeared inside the room and knelt on the ground. The empress was surprised by this sudden intrusion and asked in a calm voice, "Do you have no manners left?" 

The shadow guard did not defend herself and said, "My Liege, the centaurs have taken action."
