Now hold on, I can hear you now. How exactly can there be any connection between these two properties? Where in DragonMech is there a place for an utterly otherworldly, acid-blooded killing machine that is most at home in tight, cramped spaces? I know exactly where there is a place for them, and this place is called a City-Mech. Just think of it, a previously unknown lunar creature, or a variation on an existing creature (magically augmented nanites, anyone?), sneaks its way into the gear forest of a City-Mech, breeds at an astonishing rate, and eventually causes a noticable enough problem for the PC's to be sent in to investigate. Upon arrival, the party discovers the remains of a cogling community with signs of combat, and follow a trail of destruction to the central nest, with much suspense and ambushing along the way (humungoid queen and cocooned coglings as optional extras).
Heck, with the right steam powers, you could even make a smartgun (boiler-augmented steam gun with automator(reload)-targeter-discriminator). That, a flame nozzle, and a scanner steam power set to lunar creatures, and all that's left is for someone to shout 'Game over man! Game over!'
Obsession isn't always a good thing.
