The Vault Sealing

The Vault Sealing stands as the third documented phase of the catastrophic Sundering’s Echo, a necessary, frantic act of triage performed in the immediate hours following the cataclysm of the Great Sundering. As Chronicler, I stress that this was not a planned measure but a desperate, ad-hoc protocol initiated by surviving engineers and what few Keepers of the Cog remained. The objective was clear: prevent the volatile remnants of Umbral’s research and materials from exacerbating the disaster or falling into opportunistic hands. The primary concern was securing the most dangerous repository, the subterranean Vault of Whispers. This vault contained not only sensitive lore, but also unstable quantities of harvested Aetherium. The teams worked in thick dust, the air still poisoned by the collapse, utilizing emergency forms of Resonance Weaving to seal access tunnels with massive stone plugs. They inscribed these stoppers with hastily improvised Runes of Warding, hoping to repel the scavenging Shadow-Goblins already emerging from the deep. The sealing crew, a group of dedicated Deep-Delvers and Abbey novices, understood they were preserving future possibility at the cost of current necessity; they knowingly locked away critical knowledge that might have aided recovery. It is tragically ironic that in sealing the vault to protect the truth, they rendered vital secrets regarding Umbral’s failed Aetherium Conduits inaccessible for generations. This act of immediate preservation guaranteed stability, but it left the future Abbey blind, forcing subsequent chroniclers to work with fragmented histories. The final, desperate use of a massive Obsidian Shard cemented the main entrance, ensuring the whispers within were silenced for centuries.
