[IC] New Crobuzon & the World Beyond

[GM Marvel]

Not sure how Kubo can help right now?

[OoC: I would not have created a riddle that only one person could solve.  Everything you need to solve this is solvable by anyone in the party.  You don't need a magic spell or a weapon to hack the door down.  You just need to remember that this is riddle so you just have to figure out what the riddle is talking about.  For example...

Thirty white horses on a red hill
First they champ,
Then they stamp,
Then they stand still.

What's the answer?  Teeth!  

No magic or weapon required.
