Issac and Leon immediately head for the window, so you and the other two members of your group follow them. Issac's yanking the curtains out of the way as you walk up.
There's nothing but darkness outside. You can't even see a hint of shadow out there, and shining your flashlight out the window doesn't do anything to improve it, either. Despite the lack of raindrops on the window, you can hear a thunderstorm, distantly.
BAI
I told you. This place exists outside of everything.
KLAIR
Wh... How... What- What happens when we get out? Will it... put us back where we were?
BAI

They're cut off by a loud thud and a crack, followed by Issac jumping away from the window, holding his hand and hissing swears.
LEON
Careful! Let me see.
Leon tends to Issac's hand while you look around. It looks like there's a path between the giant bookshelves that surround you.
