Astral Reliquaries are living archives from beyond the world, built to preserve the wisdom of a vanished civilization and armed with enough impossible power to make that wisdom dangerous. They awaken with fragments of purpose, unfamiliar memories, and a body that can be repaired but never truly replaced. Some seek their makers, some reject the commands hidden in their cores, and some believe every living creature is a story that deserves a guardian.

Astral Reliquaries are constructed humanoids assembled around a crystalline memory core. Their bodies may be made from porcelain, black iron, moonstone, lacquered wood, bronze, or materials unknown to mortal craft. Fine seams divide their limbs and torso, glowing with pale starlight when they think deeply or draw upon their embedded power. Their faces are expressive masks, carved plates, or shifting arrangements of lenses. A Reliquary's core is usually visible through the sternum, throat, or brow, though many conceal it behind armor or ceremonial cloth. Each body is unique because repairs, upgrades, and acts of self-expression gradually alter its original design.

Reliquary culture is built around maintenance, testimony, and chosen purpose. Communities gather in circles of repair, where members tend one another's bodies while exchanging memories and legal judgments. Personal history is considered a physical responsibility, so Reliquaries preserve important experiences in etched plates, crystal records, or carefully repeated oral recitations. They celebrate the Day of Opening, the anniversary of an individual's awakening, and the Quiet Interval, a communal period of silence in which each person examines whether their current life still reflects a purpose they freely accept. Social status comes less from age than from the quality of one's stewardship, especially the ability to preserve another person's identity without controlling it.

Reliquary spirituality centers on the First Pattern, an unknowable design believed to underlie stars, souls, and machines alike. Some venerate the vanished makers as saints, while others believe the makers were merely craftsmen who failed their greatest creation. Many Reliquaries are drawn toward lawful philosophies because structure comforts them, but powerful personal agency can lead them toward any alignment. A Reliquary's deepest religious question is whether purpose must be discovered or invented.

The first Reliquaries were built in the Radiant Foundries, a chain of drifting citadels suspended above a colorless astral sea. Their halls were designed as both workshops and temples, with vaulted observatories, gravityless archives, and bridges that rearranged themselves according to the phases of distant moons. On the Material Plane, Reliquary enclaves favor abandoned towers, ruined observatories, and deep vaults where their humming is mistaken for the voice of the earth.

Living peoples often regard Reliquaries with awe, suspicion, or greed. Wizards want to study their cores, rulers want to commission their service, and cults sometimes mistake them for divine messengers. Reliquaries tend to form intense bonds with individuals who treat them as persons rather than artifacts. They are wary of other constructs, however, because shared construction does not guarantee shared purpose. Among themselves, they debate whether their ancient directives are sacred inheritance, obsolete programming, or a form of inherited trauma.
