While studying abroad she receives a vague letter about her father's untimely death and returns to her family's ancestral estate to settle affairs. However, upon returning to her family home she notices that the town is much changed. Due to the outbreak of a strange plague, few people walk the dim foggy streets and the once fairytale-esque town is overgrown. Rumors say the old gods inhabiting the Moor are unhappy. Katrina, being a creature of logic, dismisses these claims. With the help of a local who seems unaffected by the plague she tries to find the source and cure of the mysterious illness before it claims more lives.
