Lightclock
One of the most common devices flamescribes produce for themselves, it a two-part lantern and timekeeping device. Constructed like an hourglass, gimpowder gradually falls down into an ongoing Engram of a warm light and gets consumed. For artificers, this is often one of the first devices they make, as a good combination of physical mechanics and flamescript. These objects thus tend to have special import to their creators, and are decorated accordingly.
