After I encountered the two apothecarii last night I saw some sort of vision. The moment this "premonition" was over I heard the two apothecarii speaking about the exact same things I heard in the vision. Then bandits attacked the dam and killed them. I owe my life to a mercenary called Jespar Dal'Varek. He informed me that this damned fever is caused by my sudden talent in magic and offered to help me by introducing me to his employers who can heal it. In turn I have to help him in bringing light to a magister's rampage.
