Arcdruen Extract is a extremely lethal poison that can be fabricated from the crushed petals of the Arcdruen plant, which only grows upon the highest peak of the Otraglith. The poison is notorious for having no color, taste, or smell, and its ability to kill almost every living creature unfortunate enough to imbibe it. The peak upon which the flowers grow was historically guarded by Calphost, a task that fell to Agnahei after the god's death. Despite many attempts to destroy the plant, they invariably grow back.
