31 - The Eye of the Pit
This is a ring of very tall mountains with a thick jungle in the middle. Climbing the mountains to enter this ring, even at the low points between mountains, is extremely dangerous, as the mountains are riddled with caves (none of which lead to the inside of the circle) home to dangerous monsters. The jungle itself is barely navigatable; you can't see the sky, there's barely a difference between day and night, and any path you cut yourself through the jungle is regrown over within minutes unless under the influence of anti-magic. In fact, the whole jungle acts as a maze.
In the exact center of the ring is a lonely mountain with a tower built at the apex. At the peak of the tower is a polished brass sphere surrounded by orbiting dull grey ioun stones. The walls of the tower are covered in mysterious writting, written in the mysterious Druidic tongue.
32 - The Bonesalt Desert
The bonesalt desert is much as the name advertises. It is a desert, where the sand is made of crushed rock salt. There are few wells in this desert, and the wells that do exist are fiercely guarded by barbarian tribes who rely upon the wells for survival. I do not mean that they defend the wells from other living beings, as most of the the tribes would welcome strong warriors and wizards. No, the desert is home to many Living Horrid Wilting spells, whose only purpose seems to be to seek out and destroy all water they find, whether that water be from a well, or from a living thing.
