Lignera Note

"Research notes pertaining to a toxic crystal known as the "Poisonous Crystal, Lignera." These notes are part of a wider collection discovered in the laboratory of the magic scholar Yohan after his death. Yohan was engaged in research on magical methods for protecting against insect poisons and was testing the effects of various toxins on the human body. Poison appears to have seeped into the notes themselves, suggesting that they may have been close at hand during repeated experiments, so touching the pages with bare hands is not recommended."
