Designated among the most fearful of aspiring alchemists, or more cautious as they prefer to designate, the sourceliers spend long weeks a total asceticism on the rocky beaches of the Void to speak with the ocean and look for rocks or fluids suit their exercise. Once reached the necessary state of focus, they become able to focus very quickly to control malicious or aggressive impulses of pujlanar as any assailant.
It is this ability, despite their reluctance to approach those who remain their patients, which makes sourceliers unavoidable members of maritime expeditions for trading on the coasts of the great continent.
