Though some scholars may argue about who exactly created the first steam-powered clockwork, the secret of their manufacture is now out. Savvy engineers have started to create faster and more powerful clockwork contraptions in the form of marvels blending arcane heat sources with large boilers to create pressured steam that powers the complex constructs.

The steam-powered clockwork dragon presented here is built using the clockwork dragon.
