A by the books dark and gloomy forest, but with an unlikely protector
A place where no one knows about or finds until the Circle chooses a person to discover it. For the Circle of Culthus has a purpose for that person, and letting other people know of it or discover it would hinder that purpose.
Sharp thorns, tangled vines, and lost secrets.
An enchanted forest where music permeates the fabric of life, leaving its mark on fauna and flora alike.
A forest of perpetual Autumn
Spots of perfect green. The Ankorillian Islands. Jewels of the Blue.
A moving island, and home to both the honorable Lizardfolk and the evil Cult of Dar’Orgath.
Wise travelers know to pass wide around Destinen Wood, for few have emerged unscathed from that accursed forest.
Uncharted, and unexplored save by a few, Xenos seems a veritable paradise with plenty of food and fresh water, a godsend to any ship that finds it. Many ships have put ashore, only to find that they can never leave.
No one goes to the Western Woods. There are things that come out at night that it would be a very bad idea to meet. The Western Woods have a reputation of being haunted, or rife with wild magic. Or both.
The Dark Oak Forest is a place of darkness, danger, and Evil. For reasons best not talked about, the Dark One has visited this place, twisting it forever.
There are places in this world, which hold a weak barrier to the Spirit realm and the real world. One such place is The Spirit Glade.
After the PCs defeat (or force the rapid retreat of) a villanous necromancer/demon summoner, they discover a book. This book outlines how to summon a demon whose power increases according to the size of the summoning circle used to summon it. And after the PCs examine a map of the country, they find that the layout of the cities and roads match up with the required summoning circle. In fact, the final road that would complete the circle is currently in construction.
With anyone who can find out about the circle and the ritual to summon the demon able to somehow make the final road/line, and destruction of the cities and roads currently in existence out of the question (unless this is an evil campaign- that removes the moral quandary), how are the PCs going to solve this problem?
