My artist, Marlon Teunissen, is working on the fourth illustration of the Haeven of Punyal. This scene covers one of the steampunk devices used in this book, which doesn't have a name. It is an alerter, and I created a simple rendering of it here, so that she can use it to complete her drawing. The way it works is approximately as follows: using a flywheel (eventually steam powered, of course) a platform slowly turns around, on which a infrared sensitive lens is situated. This lens' focus is changed between certain distances, allowing the valve to open and close depending on whether a heat signature is detected (the alerter uses a similar crystal as the talker, which allows the infrared light to be focused on a valve which opens and closes). In this case the valve doesn't trigger an air stream, but a small silver rod which hits a large bell. As long as the device is powered, this means it will sound the bell each time it finds a relatively large heat signature. It therefore alerts you if there are people nearby.
