The Omega Vault is a sealed series of ancient engines, catacombs, and chambers that sits at the heart of Watch Fortress Erioch. The Omega Vault has been part of the Watch Fortress since it was established in the Jericho Reach, though what it contains at its center remains unknown to any now living. The vault itself is a broadly cylindrical portion of the Watch Fortress that spans many levels running through its core. There is only one entrance to the Omega Vault; a single door forty paces high. The door is sealed and armored by layered void shields and adamantine plating as thick as a warship’s prow. Engraved upon it are the symbols of the Deathwatch and the elder Terran rune “Omega,” surrounding an image of the Emperor strangling a coiling serpent. Above the great doors are words in High Gothic that read, “And The Last Fortress Is Truth.” Each Battle-Brother freshly stationed at the Watch Fortress is brought before these words to take his oath of vigil.
No living being can open the doors of the vault; they open themselves at the command of mysterious ancient devices at the heart of the vault itself. Those that have been inside pass along corridors and down spiraling stairs lined with catacomb sub-vaults, each barred with its own blast door and surrounded with dust-dry parchment fragments and archaic marks etched in silver. Through each door awaits a secret of the Omega Vault held in an armored chamber, each protected by powerful automated defenses and locks of unfathomable complexity.
The Omega Vault is known to yield up a portion of its cryptic artifacts and information in direct response to events unfolding within the Jericho Reach. Only one chamber has ever been discovered and unlocked each time the Omega Vault has opened itself. Once whatever waits in the chamber has been removed, the vault seals itself again, sounding a sonorous bell to warn of its closure and of the fatal consequences that follow should anyone tarry overlong.
In the past, the vault has provided tomes of archaic lore, strange fragments of alien devices, ancient weapons forged in times long gone, world-slaying virus canisters, enigmatic star charts, and bizarre xenological specimens.
At the center of the vault lies another, inner vault: a secret of secrets, bound with scores of locking mechanisms which have slowly opened themselves, one-by-one, down the centuries. The Chamber of Vigilance believes that sealed within this chamber is the final truth and, perhaps, the last weapon the Deathwatch will have need for in the Jericho Reach.
