Gears Out of Time

You have sailed to the Isla Quieta to catalogue its famous silent clockwork machines — brass giants that haven't ticked in a century. But as your dinghy scrapes the shingle, you hear something impossible: a deep rhythmic clunk from somewhere inland. Storm clouds are piling on the horizon. You have maybe twenty minutes before the squall hits and your dinghy swamps. Something on this island has woken up, and you need to find out what — and shut it down — before you run.
