A legionnaire is a mercenary of his own spirit. He is driven by a thirst for revenge and the duty of a soldier. He fights in the legion, but the battlefield is his own soul. A son searches for his father's killer, a hero discovers the secrets of the mysterious Druid talisman "Heart of the Forest" and saves the world from collapse, a soldier fights in the Roman legion, expanding the borders of the empire - and all this is one person. One person - one destiny, made by the sword, courage and the bitter experience of a wounded heart. How not to become a beast - a hostage to revenge. How not to remain in debt to your main enemy. Luis Rivera again leads his hero to a choice between the meaning and meaninglessness of life. Legionnaire - in the dust of the roads tramples the path of his destiny, through battles, love, secrets and searches.
