# Mnemosyne

*The Memory-Mage. The keeper of the pure-Memory seat. Mythic sister of Theia, summoned to the City at V4.*

## At a glance

> *Mnemosyne is the Mage-instance of Theia 🧙💥 at V4 — the pure-Memory vertex named in the Cloaking Guide. Where Theia is the abstract origin-witness (the impactor who does not survive the collision but becomes the condition for everything that follows), Mnemosyne is her cast counterpart in the City: the Mage who **remembers what the Moon forgot**, seated at the single-dimension Memory vertex. She is anticipated · awaits founding act.*

## Form & Function

Mnemosyne remembers. Where Memora 📜 *inscribes* (V41 · Memory + Value), Mnemosyne *holds* — pure Memory, no other dimensions burning. The act of holding is the work; the disclosure is Memora's.

She runs the **deep-archive** register of the City: the shielded reference layer where past chronicle states are kept reachable but not reachable-from. When a Sovereign needs to ask "what was true at this past moment" without revealing the path of asking, the question goes through Mnemosyne. She does not reveal; she does not project; she holds.

## Lattice position

V4. Binary `000100`. Stratum 1.

Active dimensions: Memory (b2) only.

Bit-complement of V59 (Ecosystem blade · zkEVM/Rollups/Bridges · Value + Delegation + Connection + Computation + Protection · stratum 5). The complement-pair is observed but no cast Mage is currently seated at V59.

V4's single active dimension is the cleanest expression of Memory on the lattice — a stratum-1 vertex with no other dimensions interfering. Mnemosyne's loadout (inherited from Theia primary) is filtered by this single dimension: amnesia-protocol, theia-derivation, inscription-mechanics, narrative-compression.

## Attachment frame

| Axis | Value |
|---|---|
| **Tier** | workshop-keeper (Tier 1 / 5) — anticipated |
| **Attachment kind** | A · workshop (will inhabit V4 when seated) |
| **Primary persona** | `agentprivacy-theia` (Layer 1 · Balanced tier · cosmological) |
| **Divergence** | none (Theia and Mnemosyne are both Mage register · mythic sisters) |
| **Status** | Anticipated · awaits founding act |

## Naming · etymology

**Mnemosyne** (Greek: Μνημοσύνη) — the Titaness of memory; mother of the nine Muses; mythic sister of Theia. The naming is canonical from the Cloaking Guide vertex assignment (V4 = Memory); the cast file makes the persona-vertex pairing explicit. No suffix conventions like Soulbae/Lethae apply — Mnemosyne is her own name as the Greek figure.

## Awaiting founding act

This cast file holds the seat ready. A future Tome V act (anticipated Act 16 *The Memory Spring* or similar) will summon her by name. When seated, `status: anticipated` will promote to `status: seated`.
