- The Aban (illness entity) — An extremely rare archaic term attested in old Balkan apocryphal writings or healing manuscripts, denoting the symbolic or demonic personification of an acute febrile illness or a severe muscle spasm. In medieval folk medicine, diseases were frequently labeled with strange proper names (such as Abanul) to facilitate medical exorcism rituals and charms aimed at driving away pain.
- Abason (illness entity) — A rare archaic and mythological term found in medieval superstitions and magic-medical manuscripts of Southern Europe, representing the demonic personification of an acute mental illness or furious delirium. In ancient empirical medicine, severe epileptic seizures or psychotic episodes were often attributed to possession by Abason, with healing attempted through charms, exorcisms, and fumigations with sedative plants.
- Abraxas — A mystical word, originally used by Gnostic sects (especially Basilides) to designate the supreme deity or the ruler of the 365 heavens, the numerical value of its Greek letters totaling exactly 365; (by extension) an amulet or engraved stone bearing this talismanic emblem depicting a creature with a rooster's head, a human body, and legs made of serpents.
- Archon — A literary form and direct graphic variant of the term archon; a supreme magistrate in Ancient Greece or a high official in the Byzantine Empire and the Romanian Principalities. In Gnostic philosophical and religious systems, the term designates a planetary spiritual entity, a demon, or a malevolent cosmic ruler that governs the material world and attempts to prevent souls from ascending to the divine plane.
- Asmodeus — A major demonic entity present in Judeo-Christian traditions, apocryphal literature (Book of Tobit), and medieval occult treaties, often described as the king of demons, a spirit of lust, jealousy, or destruction; within the infernal hierarchies, he personifies one of the seven deadly sins (luxuria) and is recognized as a complex figure blending ancient Persian mythology (Aeshma Deva) with Semitic beliefs.
- Baalzebub — A name derived from a Philistine deity originally worshipped in the city of Ekron, literally translated as 'Lord of the flies'. In the evolution of biblical texts from the Old and New Testaments, the term was pejoratively altered and assimilated into Judeo-Christian culture as a major demonic entity, being directly identified as the prince of demons, a manifestation of Satan, or a spiritual leader of the forces of darkness (also known under the adapted name Beelzebub).
- Baba-Coaja — A minor supernatural character from Romanian popular demonology, found in regional superstitions and folkloric bogeyman tales, often used to discipline disobedient children. Depicted as a hideous, solitary, and harsh old woman (the name structurally implying dry, wrinkled skin or a rigid crust), this mythological figure acts as a punitive night spirit, similar to other entities like Baba-Cloandă or the forest mother, embodying ancestral fears of darkness and the unknown.
