The Book of Beasts

Jonur, a biology student at the University of Selath, doesn't believe in demons or magic. He thinks there's a rational explanation why almost nothing lives in the area around Lake Forsaken. As he and his partner collect samples from the area, they become sick themselves. Then Jonur encounters a foreign girl with a stranger book. She claims the area is poisoned and that Jonur and his partner are now affected. However, she plans to use her book to create an animal that can neutralize the poison. Who is this girl? Can she and Jonur work together to fulfill her plan, or will she let him die?
