Scouting
Cinder scouts around the theatre.
Cinder climbs to the roof. Looking down, you can see a couple things of interest. First, in one of the box seats, you see a corpse! There is a body lying face down, a cloak covering most of it, but you can see some fancy clothes and gloves that have resisted the decay of this place.
Also, each of the three insects flying around seem to be jeweled.
The 'Performers Only' door opens to reveal a small musicians' prep room. There are a couple of benches and seats, a viola case standing in the corner (which will be found to be empty), and a glass case against the wall. In the case are two wands, each with a small tag attached. A white wand is labeled 'In case of emergency N' and a red wand is labeled 'In case of emergency F'. There is no obvious way to open the case.
The lantern, on further investigation, is a large shuttered contraption, roughly a meter tall by half a meter diameter.. Its movements reflect aspects both mechanical and magical, as there are many shutters of different location and width, all sliding back and forth at random. There is a small switch at the base, and what appears to be a small door that would open to the inside of the lantern. The switch is found to stop all movements of the various shutters when flipped down; when flipped back up, the movements haltingly begin and then get back to it.
No traps to be found in the theatre.
Searching out in the mechanical wasteland, you find an old hatrack, two broken javelins, an enormous metal cube (three meters square), the hull of a metal caravan, a suit of plate mail in terrible condition, two lances, a broadsword, and a halberd. Plus the aforementioned glaive-guisarme.
