The Roof is pretty self-explanatory; it's accessible to any character. It gives off an, "I'm on top of the world" vibe and allows fresh air to fill one's lungs. Honestly, it's one of the more chill places to be.
If the Multiline is damaged, then The Roof's condition can become not so chill.
- There could be an overpowering presence that makes those on the roof feel small instead...
- The fresh air could become polluted, and hurt the lungs of those who inhale it if they are prone.
- Its accessibility could be taken away.
