Seamwalkers, Prompt 18

>> examine rocket

The small but menacing-looking rocket is pointed west where you can see a very thin, door-shaped fault in the cliff wall. There's some writing etched in the wall above the fault. On a table next to the rocket is a fuse and an empty tube labelled 'ENGINE.' One end of the fuse is attached to an ignitor box with a push handle. The other end is attached to the tube.
