Into the Mournland

Publisher's blurb:

The expedition had set out with grand ambitions, but what they found was a world beyond their worst nightmares. As they pushed further into the Mournland, the group of over a hundred adventurers dwindled down to a mere handful of brave souls. They faced hunger, thirst, and the relentless attacks of unspeakable creatures, until they stumbled upon the ruins of an old watchtower. But the respite was short-lived, for a hidden terror lurked within its walls, ready to strike.
