A lazy and quiet type of Wisp, the Argons came to be when many souls ended their life bed-ridden and weak, leaving their pent-up desires cut short by their weakening bodies, becoming spirits displeased with the world to the point of prefering a nihilistic afterlife. Argon Wisps prefer to be worshipped, becoming hypnoticaly alluring to their victims so they spend the rest of their lives fulfilling the Wisp's unrequited desires.
Argon Wisps can be easily avoided by adding a fluffy pillow underneath the head of it's corpse.
