The Hawkman RPG

WARNING - NSFW

The hawkmen race were exterminated 10 years ago by orders of the human king. One of them survived and will have his revenge by taking over the kingdom and impregnating human women to recreate his race.

The game centers around the mechanic of stealing souls from monsters to increase your power: Your goal during random battles is to decrease the enemy's health to <20% and cast the "devour soul" spell on them. Devouring an enemy's soul will give points (amount based on level) which you can use to increase the main character's attributes.
