Mare — the sea — is the only domain of the catalogue whose Founding-era slot is formally registered as not applicable. This is a doctrinal finding, not a deferral, and it rests on three reasons:
- No founding wet-navy. The founding Republic had no maritime arm. Its Citizens fought on the ground, in atmosphere and in the void; the seas of the founding worlds were not contested at a level that required a Republic combat hull. The Adamant Forge — which built for every other domain at the founding — did not lay a single wet-water hull, by design.
- The wet-water Forge is post-founding. It was raised in the Modern era, when the Republic's expansion onto worlds with significant oceans required a regular wet-water service. The entire Mare catalogue is Modern-era only; there is no Vigil-era Mare roster either.
- The Adyton does not build for sea. The Imperial Armada is the void fleet, not a maritime force; there is no Imperial wet-navy, and none is expected.
The doctrinal consequence is written into every entry: the lineage field reads as empty for every Class in the domain. The lineage opens at the Modern era with no founding or Vigil ancestor. The Republic's wet-navy is uniquely young, unburdened by heritage, and without an Imperial parallel — which is exactly the doctrinal signature its own war doctrine registers as the Republic's learning service.
The roster is closed at eight Classes. No future Founding-era expansion is planned or possible; the doctrine does not admit one.
- Breakwater — Patrol Vessel. The close-shore work and the territorial watch.
- Surge — Surface Combatant. The screen of the line.
- Seawall — Capital Surface Hull. The flagship and the anchor of the line.
- Beachhead — Amphibious Assault. Sea-to-shore landing.
- Promontory — Coastal Defence Platform. Fixed, anchored to a headland or a strait's mouth; the redoubt the line falls back to.
- Deepwatch — Submersible. The only Republic combat hull whose primary doctrine is to not be seen.
- Tidedeck — Seaborne Carrier. The wing's home at sea.
- Ferryman — Auxiliary. Fuel, ammunition, tender work.
Eight Classes, all from one Forge, all Modern by design. The domain has no heritage line to draw on, and the doctrine treats that as a defining feature rather than a lack.
