Mt. Glenn, RWBY Universe, Episode 26
Yang is walking back to the campsite.
Yang: Hey Weiss, it's your... Ruby? Hey, where's Ruby?
Oobleck: What?
Zwei comes running into the room, barking.
Yang: Zwei?
Blake: What's going on?
Oobleck: Grab your weapons! Your leader may be in trouble.
With Ruby
Ruby awakes to the two WF Guards who caught her dragging her by both arms through the underground city. All around her, White Fang members are at work, doing various things such as piloting a Paladin to carry large shipping containers. There is a loud sound nearby as one of the White Fang members drops a large device.
WF Guard 3: Hey, be careful! What are you trying to do, blow us to the moon?
WF Guard 4: Sorry sir!
Perry: Hey boss! Found something you might want to see!
Roman leans out through the doorway and sees Ruby.
Roman: That would be bad.
With Zwei, Oobleck and WBY
Zwei leads Oobleck, Weiss, Blake, and Yang to the hole that Ruby fell into, and Yang spots Crescent Rose next to the hole.
Yang: Ruby's scythe!
Blake: Oh no.
Weiss: Do you think she fell?
Oobleck looks up.
Oobleck: Fell?
Weiss: Down there.
Oobleck looks down at the hole.
Oobleck: Oh my. Of course! Of course, OF COURSE, OF COURSE!
Blake: What is it?
Oobleck: How could I be so stupid?!
Yang: Dr. Oobleck, what's wrong?
Oobleck: Mountain Glenn! Yes, an expansion of Vale that was inevitably destroyed by creatures of Grimm! Previously home to thousands of people! Working people commuting to the city, the main city! Developed a subway system to the inner city! Grimm attacks increased! Population in danger, now desperately searching for shelter! City evacuates into the metro tunnels and what do they find? The southeast quadrant of Vale is known for wild forests and deep caves!
Yang: Doc, what are you saying?
Oobleck: My dear, we're not just looking for an underground crime network, we're looking for an UNDERGROUND crime network!
Blake: They've been working in caves?
Oobleck: No, no, Mountain Glenn was Vale's first serious attempt at expansion. It worked for a short period of time, thanks to an aggressive perimeter defense, and unique transportation; the city developed an elaborate subway system to carry citizens safely from the new territory into the main Kingdom! Sadly, without the many natural barriers Vale had to protect its borders, Mountain Glenn was doomed from the start! As the end drew near, the citizens of the territory made one last attempt at survival: They took up shelter beneath the city! In massive caves that they had cleared out for the subway. And they had cut themselves off from the surface!
Yang: An underground village?
Oobleck: In a matter of speaking, yes. A safe haven. Until... an explosion opened the mouth of another cavern, filled with subterranean Grimm. After that, the Kingdom officially sealed off the tunnels, creating the world's largest tomb. If Ruby is down there.
