The places where the vault meets the body.
AION is a cryptographic system. The sanctuaries are the physical places where its rituals — sealing, witnessing, heir attestation — gain bodily presence. They are not data centers. They are architecture, in the older sense.
Quiet rooms with weight
A sanctuary is a small, well-built space in the city of one of the seven sovereigns. It does not store the ciphertext or the shards — those live in their respective sovereign clouds. A sanctuary holds the ceremonial layer: a witness room for sealings, a credential room for heir attestation, a quiet bay for elderly holders to record voice and letter, and the printing of physical sealing certificates on parchment-grade paper.
Three things software cannot do
Bodily attestation. Proof-of-pilgrimage — the convergence layer that defeats AI-only inheritance — is attested only when a heir is physically present. That cannot happen on a phone.
Material durability. Synthetic-quartz and paper QR backups for the highest-tier vaults are minted at the sanctuary, then placed under physical custody.
Trust that does not depend on a screen. A sanctuary visit lets a holder meet AION as a place, not just as a website. Some holders will never need this. For some, it is the only way trust is real.
First city, undecided
The first sanctuary is a Phase 3 commitment. The candidate cities are Zurich, Singapore, and Reykjavik — chosen for neutrality, legal maturity, and architectural dignity. The final selection is recorded as Open Question 5 in the planning Codex. When it is settled and a building is leased, this page lists the address, the architect, and the open hours.
There is no sanctuary today
Today the sanctuaries are a doctrine, not a site visit. AION will not photograph empty rooms and call them a network. When the first room is real, it will appear here with its photographs. Until then, the page reads as it does.
