Arnthalirs problem

Quest Description
Find and assist Arnthalir the elf if you are able to. He was last seen near the forest of Wayreth, north of Cormallen.

The Wayreth Woods
You can find Arnthalir just outside the Wayreth Woods. Leave east from Cormallen and head north until you can turn west. Continue west past the Tower of High Sorcery and you will find Arnthalir the elf

The Imp King
If you say "quest" to Arnthalir, he will tell you how he has lost a valuable ring to the imps in the forest, and how he suspects the king will have it. Heading west into the forest you will encounter many various magical Imps, as well as the Imp King.

Imps will call for help and any friendly imps in the area will quickly come to their aid. Fighting solo imps is not difficult, but dozens at once is tough to survive.

The Ring
When you kill the Imp King a ring drops from his corpse on the floor. You can now get the beautiful ring and return it to Arnthalir.
