Riven The Conqueror:

They say great leaders are forged.

In this matter, Riven was made for the sole purpose of conquering as much land as possible in as little time.

Made from various parts of people in the depths of hell, Riven was to be the perfect weapon.

No sooner had the ground, that spat him out, cooled off, Riven had already killed his first person.

Naked, cold, and fearless Riven began his conquest of Rhy'Din.

It was not long before Riven encountered a group of soldiers to  follow him.

A journal that has been uncovered tells more, written in Riven's own hand.
