Received from: Automatically after finding "South-Song" Gerralt's Corpse [Sundermount - Abandoned thaig]
Finding Gerralt's remains won't be easy and it will be connected with at least one VERY DIFFICULT battle. I suggest you to start looking for them when your teammates are developed enough. Go to the localization [Sundermount - Dalish Camp]. After reaching the northern part of the camp choose the path on the left #1, which leads directly to north-west. Here go straight. Look around near the exit from this map and you will notice the entrance to the cave #2 (M25, 13). It leads to the localization [Sundermount - Abandoned thaig] (M57, 1).
Watch out for the fire traps ahead of you #1. As you probably suspect, you have to wait for the moments when the traps are turned off and then pass. After reaching the crossroads from the north first stone golem will run towards you #2. This beast is known to you from your trip to Deep Paths so you are aware they shouldn't be depreciate it.
Now you can head towards the doors leading to the northern room #1. Unfortunately there is a difficult fight ahead of you. At the beginning you will find corpses, archers' skeletons, another stone golem as well as living dead #2. First you should eliminate living dead because it can influence living corpses.
Later in the battle you will also face the demon of anger #1 and it is worth dealing with him after defeating the living dead. Watch out for fire attacks performed by the demon as they can take many health points away from your teammates. After the battle's end, choose the eastern door #2.
Do not use the stairs in front of you. Instead check the area near opened door and you will find Gerralt's remains, "The Song of the South" #1 (M57, 2). You can leave the area and during the day go to localization [Lowtown - Market]. Here find Gerralt "Eastern" #2 (M12, 19). As a reward for passing him the remains you will obtain 1 sovereign.
