Against Test Subject-03!

As it sought food to eat and devour, the beast was stopped by him, the green feathered dragon.
Both fought desperately, the dragon was weak, yet it held the power to stop it, those blasted winds, they hurt like nothing before when they pierced and slashed its body.
It ran away, desperate to not be hurt anymore, swearing to come back again once more.
As it recovered within the depths of the ruins, its own toxicity spread like spores across the village taking shelter around the dungeon.
Without knowing, the people that were too weak to resist were infected by this spore, and "marked" by the beast.
And when it came back, it sought them, its meals.
It needed to feed desperately, it had not feed for too long, it needed blood and flesh, souls, even!
However, the dragon was there again, stopping it from taking as many as it wanted, and then more came interrupting its meal.
