Aurora In The Sky

Kruv- A young commander of an army found himself surrounded by hundreds of thousands of enemies. He smiled and fought on yet he knew he was going to lose.
After lying down on the ground after getting struck, the last thing he saw was a streaks of thick lightning with 9 different colors and then after that was blank.

When he opened his eyes, he found out that he has not only been reincarnated but has also been transported to another world. A world where strength rules, a world where beasts cause havoc in towns and cities, a world where people have power called innate ability.

What will Kruv's destiny in this world be? Will he find enemies? Allies? Or both?
