Phosphorus

Phosphorus is a highly reactive element found in Galfin, it can be found in various allotropes, including white, red and black. It is a relatively rare element, and because of its reactivity, it's only handled by skilled alchemists. In Galfin, Alchemists view Phosphorus as a material with potential uses in alchemy due to its ability to ignite easily and its potential to be used in creating magical illumination. It can be used in creating light sources, such as phosphorescent powders or potions, and in alchemical processes that require intense heat or light. It's not commonly used in trade or crafting, due to its reactivity and flammability, making it hard to handle and store. It could have some use as a tool in mining and smelting, but only with great care.
