Eltheria

“Its towers touch the sea floor. Its silence touches the soul.”

Eltheria is one of the five legendary Ancient Super Cities, located deep beneath the surface of the ocean. It is built vertically in layered concentric plates that descend from a wide top to the seafloor below.

Originally believed to be a military research facility, its design is a testament to structured defense, compartmentalization, and containment. Little is known about its specific operations, but its hostility and mechanical defenses remain active to this day.

Architecture

• Structured in tiered plates, each layer potentially housing thousands
• Defensive installations remain active — including automated drone strikes and sonic repulsion fields
• Made of reinforced alloys and seamless bio-alloy seals
• Entering even the outermost tier is considered near-suicidal

---

Current Threat Level

• Entirely overrun by Necrotics
• Unknown number of defensive systems still operational
• No known surviving expeditions
• Psychic disturbances reported by vessels passing nearby — rumors only

Symbolism & Reputation

Eltheria is the most feared and least explored of the Ancient Super Cities. Its impossible structure and violent defenses make it a city cloaked in mystery, silence, and whispers.

To most, Eltheria is:

• A cursed zone
• A place where death is patient
• The most impenetrable vault in the world

“Eltheria never fell. It opened the door.” — Unknown sailor’s proverb
