Vengeance from the Grave

 is a task in.

Synopsis
While exploring the Valewood wilderness, you happened upon a small cave where a great bear lived. In that cave was a half eaten corpse and a spirit that revealed the final moment of the man's life.

Overview

 * 1) Talk to Nonton in Valewood.
 * 2) Read Perly's soul in the cave in Valewood.
 * 3) Talk to Nonton and Ingroed in Ingroed's House in Gilded Vale.

Walkthrough

 * Optional: After arriving in Valewood for the first time, head south over the road until you reach a tent and a man named Nonton, and speak with him. He will inform you about the bear cave.
 * Once you're of a sufficient level or picked up Eder and Aloth, return to Valewood and head for the cave in the north-west. Kill the bear (and her cubs on hard or Path of the Damned difficulty). Interact with the spirit, Perly, and witness his last moments. Promise to get him justice. This will start the quest.
 * Note: If The Watcher has already slayed the bear but has not yet discovered Perly's fate, Nonton can be notified of the beast's death for additional Gilded Vale: Minor Positive reputation.
 * Go to the Gilded Vale and enter the second house on the right-hand side, Ingroed's House. Approach Nonton and Ingroed and the conversation will start automatically, tell him you know what he did. You can choose to let them leave Gilded Vale, say you'll report them to a Magistrate, or attack them. If you say you'll report them they will attack you, requiring you to kill them. If you let them go, you can later find them in The Charred Barrel in Defiance Bay.
 * Optional: If you want, you can report Perly's murder to Urgeat, the magistrate. Because you don't have any evidence beside your vision, he won't actually do anything, and will tell you to be careful with your accusations. This interaction is available even if you've already completed the task.
