Nay-Theist: With the minor twist that a portion of the faction are theists, believing in a (non-personified) Great Unknown.Even so, most non-Athar in Sigil are generally uneasy about being around them, especially since they've set up shop in the Shattered Temple of Aoskar, a location that's bad luck for a whole other set of reasons. The Jinx: The gods cannot do anything directly to cause 'bad luck' to the Athar from outside Sigil, and the power of their unbelief even immunizes them against most divine magic that would do this (see No-Sell).Illegal Religion: They have a certain degree of protection thanks to being recognized by the Lady as one of Sigil's fifteen factions, but the Harmonium, Sigil's City Guards, considers them an enemy and their actions are subject to constant harassment, including discriminatory policing for their sermons and pamphleteering as 'disturbing the peace'.Honor Before Reason: A disadvantage of being a member is that an Athar is not allowed to accept aid from clerics of specific deities this includes healing magic, should the Athar be injured.Since the factions are by definition based on philosophical beliefs, those with a more common real-world atheist outlook - those who simply regard atheism as a lack of belief, rather than a belief system in itself - would not be members of this faction.Rather than questioning the existence of gods (as such things demonstrably exist in the setting), the Athar object to people worshipping what they consider to be simply powerful natural beings.Athar tactics include a lot of stereotypical atheist tactics, like trying to Logic Bomb priests or induce crises of faith.Meanwhile, their current factol became who he is when he realised that it was his own intellect and intuition that had helped him through every problem in his life, rather than the aid of his goddess, Mishkal.Their founders were Dunn (a man who wanted Poseidon to die because Poseidon and his church had taken all his possessions, his wife had been seduced into being a Poseidon priest's concubine, and his daughter had been stolen to Arborea by a proxy of Poseidon), and Ciro (a dispossessed Loki priest who wondered why gods, who should be beyond such things, would be dependent upon the faith of others for their power).Hollywood Atheist: There is a strong vibe of this to the Athar.Fire-Forged Friends: They and the Godsmen were once enemies, until they figured out their ideas were not that different they became close allies as a result.The more zealous Athar hope for the day their faction grows in power enough to cleanse Sigil of the gods' minions completely this way. Banishing Ritual: The most powerful Athar-specific ability is a ritual they have developed that allows four of them acting in concert to banish any servant of a deity from Sigil to their patron deity's realm.A few remain behind, hiding in the Undercity of Sigil.

The Faction War sees Terrance Mazed by the Lady of Pain, and the Athar are forced to mostly quit the City of Doors to instead set up a new city for themselves at the base of the Spire, where the powers can't reach them. Their Factol prior to the Faction War is Terrance, a male planar human of Lawful Good alignment, who is a 19th level Priest of the Great Unknown.

Their headquarters is the Shattered Temple in the Lower Ward. Athar (the Lost, the Defiers)A faction dedicated to proving that the powers that rule the Outer Planes are not 'gods' as they claim to be, but frauds who must be overthrown for the good of the multiverse.
