Gastrines

Gastrines are fleshy, muscle like objects which power machinery such as trains, streetcars, lights, airships (also known as Gastronaughts), and even small and intricate things such as pocket watches. Gastrines were developed after The Fall of Technology, and have been used to maintain machinery ever since.

Gastrines are created using a complex magical process, in which a summoner concentrates magical energy, creating the flesh, until the required muscle is complete. This process is most commonly associated with The Fellowship of the Practical Arcane, which specializes in creating and selling gastrines for many purposes.
