Location from Volume 2 by Rooster Teeth
A failed expansion of Vale — a ruined city overrun by Grimm, with underground tunnels that the White Fang is using as a staging ground for an assault on Vale.
Mountain Glenn is Vale's greatest failure made concrete. What was supposed to be the kingdom's first major expansion beyond the walls became a mass grave. The surface settlement was overrun by Grimm within years, and the survivors retreated underground into tunnels and rail infrastructure, sealing themselves in. Then the underground fell too. Now it's a layered ruin — collapsed buildings on the surface patrolled by packs of Grimm, and rail tunnels below filled with rubble, old train cars, and White Fang operations. Team RWBY's mission with Doctor Oobleck brings them here. The surface ruins are desolate and dangerous — Grimm nesting in every shadow, buildings that collapse without warning, the constant awareness that civilization tried and failed here. Below the surface, the White Fang has turned the old rail tunnels into a military staging area, loading a train with explosive Dust and Grimm-attracting devices aimed at breaching Vale's walls from underground. The air below smells of mold and Dust residue. Emergency lighting flickers in sections where the generators still run. Every shadow might be a Grimm or a White Fang sentry. This is where the conspiracy hiding beneath Vale becomes impossible to ignore.
A failed expansion of Vale — a ruined city reclaimed by Grimm after a catastrophic breach. Collapsed buildings, shattered streets, and an underground metro system where survivors briefly sheltered before being overrun. Now a ghost town crawling with Grimm, used by Roman Torchwick and the White Fang as a staging ground for a breach attack on Vale. The ruins are a stark monument to humanity's hubris in pushing beyond safe borders.
