The Lost Relic Walkthrough
This quest can be taken from Dugath in the Kellid Barbarian Camp. This territory is located on the right edge of the map, on the latitude similar to Varnhold’s, at a T-junction. Go there, pass the test (saving beforehand), and then chat with a character over there to learn about his objective.
Complete Along the Cold Trail quest, where you try to find all the Defaced Sisters, then beat the barbarians so Dugath will tell you where to find the relic. Head down from the camp to find the location called the Valley of the Dead. It is near the mountains. Make sure that you have three Cyclops Incense Burners in your inventory. You will receive them in three different places during the Along the Cold Trail quest.
It is important to note that while the Burners are considered to be quest items, you will have an opportunity to sell them. Do not do this. Moreover, do not sell the incense burners to the merchant in the barbarian camp, as you will probably kill him at the end of the aforementioned quest and will not be able to recover them.
Go to the gates and select the option to use your Incense Burners. Then head to the Vordakai’s Tomb. You are in for a long exploration of the tomb, which has two floors. In the end, you will fight Vordakai and his raven. Defeat them. If you decide to take Tristian with you, he will disappear with the Vordakai’s Eye. Go left and get out of there. Decide what to do with the soul vessels. It is better to free everyone. Then talk to Varn. He will serve you, and Varnhold will automatically join your state as a result. This will be a voluntary annexation, required for the Annexation kingdom quest.
Wait for Tristian to come back, and move on to the next chapter.
