KnightQuest - Part 16: No stairway? Denied!

Last time on KnightQuest:
You awaken in a strange, hot and red place after tearing a hole in reality with the Boxatrix.
You find Valarie with you and, after checking if she is ok, explore.
As it turns out, you're in hell! But don't worry, you didn't die, you only got sucked in.
After interrogating a demon, you find that the only way out is past a hellknight and up some stairs, but it'll take some convincing…

So here you are, stuck in hell, your friends lost somewhere and your only way out blocked by a demon.
Probably not the way you envisioned your quest going, but hey. That's the way the sweetroll crumbles.

go north!

Strike the knight with the broken sword

You head north, to the room you've not visited.

"It's a broom closet. Congratulations. You did it." Valarie sighs
This is where you would have thrown the bug if he'd gotten rowdy when collecting information from him.

Seems the only other path, besides the exit, is into the workplace.
