Evergreen Grove

Description
The grove is located in the Falkreath Hold region of Skyrim. The grove is actually a partially sunken ancient standing stone site that has become a pond, fed by stream in the north edge. The grove is protected by two Spriggans and possibly a Spriggan Matron. There is a cracked tomb in the middle of the pond, and a dead alchemist floating in the water. There are also various insects as well as Thistle Branch plants that grow here.

Alchemist's Camp
If you follow the stream from the pond, you will come to the camp of the dead Alchemist where you will find the Alchemist's Journal, ingredients, a skill book and three Nirnroot.

Notable Loot

 * Skill Book: Mannimarco, King of Worms - increases alchemy
 * Skill Book: De Rerum Dirennis - increases alchemy

Crafting
This is good site for alchemists due to the two skill books and variety of ingredients here.
