From the introduction:
Deep within Ravenswood the land becomes jagged and broken, dying ferns cover the ground, black drops of water dripping slowly off their slimy leaves from the rains the night before. Bones and other debris are scattered among the dirty ground and between the eroded lands, large roots have grown, or what seams more likely have been magically placed.
A giant tree stands before you, a large jagged hole leading deeper into it’s interior. You follow a staircase carved into the wood and are lead into the heart of the dark tree. A pot of bubbling stew sits atop a gently burning fire, it’s light illuminating this chamber. A small table carved from the trees wall, holds grimy alchemy supplies, strange crystals and a book in a strange language.
Another set of stairs finally lead you up to a ritual site, where hundreds of skulls lies piled around a symbol of great evil, pulsating with eerie decaying light.
