Aghasuras, or the poison ones, are massive fiends who have perfected the art of ambush and hold to duties of guardianship and butchery. It is said that these frightful ophidian monsters came into being when a deity granted free will to her favorite serpent pets, but when these pets were left to their own devices, they slipped into the deity's favored temple and slew all of her greatest priests. The serpents who survived the deity's wrath became the first aghasuras.
