An archaic or variant term for an avenging spirit or demon in classical mythology.
From Greek 'alastor' meaning an avenging spirit sent by the gods. This term appears in classical texts and carries the weight of divine punishment, related to words like 'ala' (to wander) and concepts of curse.
In ancient Greek and Latin literature, an alaster was basically a supernatural bounty hunter—a vengeful spirit sent specifically to make sure you paid for your crimes against the gods, which is way scarier than any modern punishment system!
