- Body plan
- A handspan mantle with dozens of cilia and one dense memory pearl, suspended inside a tall faceted shell with three precise manipulator arms.
- Senses
- Radiation gradients, polarized light, surface chemistry, vibration, and the electromagnetic signatures of authenticated documents.
- Life cycle
- Larvae are raised in audit pools, then apprentice inside low-status shells. Adults periodically copy certified memories into a successor pearl, creating disputed but legally useful continuity.
- Native environment
- Mineral brine caves under a bright variable star, with lethal surface radiation and rich crystal growth.
- Social unit
- The account household, a legal lineage composed of shells, occupants, dependents, and enduring obligations.
- Notable trait
- Oru can smell forgery because authenticated inks are inoculated with living enzymes keyed to the issuing account.
- Homeworld
- Aurelia. Prosperous but heavily enclosed; its oldest cave cities are now vault-temples and arbitration markets.
- Founding event
- The first communal survival shell was granted legal continuity so maintenance debts would remain enforceable across generations.
- Historical wound
- A century-long identity panic followed the discovery that three major shell lineages had copied the same founder memory and each claimed to be the original creditor.
- Current aim
- Make Aurelian contract law the default infrastructure of interstellar trade, so every route eventually passes through a Syndicate ledger.
