Dark and musty, the Wizard's Quarters are filled with ancient tomes and mysterious items.  Scrolls and jars of mysterious reagents line the walls of the Wizard's Quarters, and magical lights flicker with a mysterious green flame.
Wizard's Quarters, Outside Tower
a cat
roach
I am a roach living under the floor. I fancy going out at night. Avoiding shoe bottoms is my daily life.
...scuttle? Meow.  Prepare to be eaten. Here, take a drink of this instead. I promise it's good stuff. Let me try! Enjoy being a roach like me! I will turn all the world into roaches! You spoke too soon, now I know not to drink that.  You will be my lunch now. Engarde! Now casting EXPELLIARMUS! I'll blind you before you can read it! You don't know how to use those.  I have seen the wizard use them.  They are dangerous, if you handle them incorrectly you'll kill us both! Look at us! Fighting like we haven't been friends for years! Combining the lights with the potion will now turn you into another cat.  Meow.
