Centaur's Iron

The Centaur's Iron, colloquially known as seeyai, is a magical vapor manufactured by New Horizon. Seeyai was first created c. Y170, although the exact details of its discovery are lost to history. Over the ensuing decades, the relationship between seeyai, New Horizon, the Unity Bloc, and the Centaur Gruss Maguff became increasingly entangled, as a Unity-led Bautriaria achieved de facto political and economic hegemony across Rhysalia. Maguff and his operatives signed a series of trade deals with nearly every town and city on the continent resulting in heretofore unseen levels of economic interdependence between regions.

Seeyai can be made in a variety of colors, and it is used for lighting as well as powering the vast majority of magical devices in Rhysalia. The manufacturing process is a well-kept secret, as New Horizon maintains patents on the production techniques involved. The substance appears to glow, and is typically kept in glass tubes or bulbs called piping to display as light sources. Far smaller, more intricate piping, using finer glass, can be used to power devices as complex as vehicles or firearms.

Functions
Seeyai's first function is as a light source. It can be made in a variety of colors - most commonly white, but almost any color can be made. True black is very difficult to accomplish, however, as the substance glows.
