Tinleaf

This metallic leaf grows in magical forests in and around the Phyloctæte. The byproduct of an insane mage's attempts to develop a metal which could be powered by plants, this flaky substance is often used as a spell component.

In addition, tinleaf is used to build automatons by these very mages. The discovery of tinleaf has made possible the very construction of inanimate constructs which do not require outside magic at all. This worries even the mages of the land.

Tinleaf is particularly potent in magic that deals with time, and artisans occasionally use low grade tinleaf to create self-powered hands on clocks, as well as other uses that follow predefined patterns and schedules, such as self-powered carts.
