Journal Entry

 * "The vodyanoi are an ancient, sentient race. They worship their own gods, and their priests deal with divine matters. Land dwellers know little of these underwater creatures and the cults which flourish among them, and what is known inspires fear. Deities of the deep lend their powers to vodyanoi priests, enabling them to cast curses and spells."

 * In Act IV, an "Old peasant" at the Inn will ask Geralt if Foltest sent him to deal with the fishpeople. Talking with him unlocks Vodyanoi Priests and their alchemies.  (He also alludes to Dagon but gives no bestiary entry for him.  You may have to advance The Heat of the Day quest to the point of meeting the Midday Bride before this conversation is available.)
