[ Ocean Zones ]
[UPDATED - 2026-07-29]
Ocean Zones organize major sailing environments and hazards in RELL Seas. Current evidence supports named sea identifiers, sky content in C3, extensive underwater content in C4, and hazards such as tsunami areas and sinkholes, but it does not support a simple invented level ladder.
Ocean hazards
qualitative risk, not a damage valueStorm zonesMedium risk
Weather can create dangerous sailing conditions. The complete list of storm effects and ship interactions remains incomplete.

SinkholesHigh risk
Sinkholes connect the surface and underwater traversal concepts. Their exact pull range and access rules have not been published.

Known sea identifiers
| Sea | Published identity | What is known |
|---|---|---|
| C1 | [Name pending] | A documented sea identifier. Its official name, spawn rules, and progression requirements are not yet published. |
| C2 | [Name pending] | A documented sea identifier. Its official name, content boundaries, and progression requirements are not yet published. |
| C3 | Sky sea | Developer notes and footage connect C3 with sky islands, sky ships, sky beasts, and aerial traversal. Exact entry requirements remain incomplete. |
| C4 | [Name pending] | Developers stated that most underwater content is planned for C4. A submarine or another ship-based method is involved, but the alternative method was deliberately not fully revealed. |
Reading the sea labels
C1 through C4 are documented identifiers, not a complete published level ladder. The page does not assign invented island names, recommended ship classes, or character-level gates to them.
Frequently asked questions
What are Ocean Zones in RELL Seas?
Ocean Zones are large sailing environments and hazard areas. Current evidence connects them with tsunami zones, sinkholes, sky content in C3, and extensive underwater content in C4.
What do C1, C2, C3, and C4 mean?
They are documented sea identifiers. C3 is associated with sky content and C4 with extensive underwater content, while the official names and complete rules for every sea are still incomplete.
Is C3 the sky sea?
Available developer notes and footage connect C3 with sky ships, sky beasts, sky islands, and aerial traversal. The exact access requirements have not been fully published.
Do you need a submarine for C4?
Developers said a submarine can be used to reach C4 and hinted at another ship-based method without fully revealing it. Most underwater content is planned for that sea.
