Head to the mountain east of Rellekka until you come to a guard who is guarding a rockslide. If you attempt to climb over he will stop you.
Head north and take the path to a boulder with a 'push' option. Use your rope on this and you will climb down to the path which the guard is guarding. Now head east until you come to the mountain camp. You will see the large tent with the quest icon in it; enter and speak to Hamal the Chieftain. Ask him why everone is so hostile to you. After a rather long conversation he will tell you that his daughter has gone missing. After completing the conversation you are instructed to find his daughter. You will also be given limited access to the camp.
The Daughter - A Voice From The Past
Head south of the tent and you will find roots in mud. Dig-below roots with your bare hands to get mud. Now head to the tent area north of Hamal and take a pole and a plank. Head north and then west on the path from there until you run into Ragnar. He will tell you about Asleif and how he was going to marry her and how he still hears her singing.
Just beside Ragnar is a tall tree. Use your mud that you dug up on the tree. Now climb the tree ti the next island. Now use your pole with the clump of rocks to jump to the next island. Finally use your plank with the flat stone to make a bridge.
On the north side of the current island 'listen-to Shining pool'. You will listen to the spirit of Asleif which will ask you two favors; to make peace with Rellekka and to find a new food source for her people.
Go and talk to Hamal about the people of Rellekka. He will tell you that they are already working on some terms with Rellekka but their representative, Svidi, has not been heard from for days.
Now head out of the camp and head to the Swaying tree (from Fremennik Trials). From the tree head directly north until you reach the black unicorns and around there you will find Svidi wandering around endlessly. Work on persuading him with a "guarantee of safe passage."
Now head to Rellekka and speak to Bundt the Chieftain who is located in the long house when you first enter Rellekka. He will tell you that he will meet with Svidi on one condition; if they receive their ancient rock. Head back to the Mountain Camp and enter in the southern hut. Use your pickaxe on the rock to get a piece of it. Go back to Rellekka and give the rock to Bundt. He will give you the 'safety guarantee'. Give it to Svidi and you will be done with your 'public affairs duty'.
New Food Supply
Your task it to find a new food supply for the camp. Talk to Jokul at the goat farm area (where you found the plank and pole). He will tell you about a special fruit call White Pearl. The place to find this is at White Wolf Mountain. Head there and pick some from the thorny bushes by the gnome glider while wearing your gloves. Eat it to get the seed. Take the seed to Hamal and talk to him about Rellekka also.
Finding Asleif's Body
Go and talk to Asleif again. She will want you to do one more task for her - to find her body.
From the middle island walk into the water to cross to the main land. Head east until you come across some dead trees blocking a cave. Chop down the trees and enter the cave. You will come across a bear named The Kendal. After a conversation you will find out that the corpse of Asleif is in the cave. Demand the body be returned. Once this happens you will end up fighting him. Kill him and take the corpse.
Go and talk to Hamal and show him his daughters corpse. He will ask you to bury her on the island which you spoke to her spirit on. You will need to collect 5 rocks from around the camp and find one possession of hers. They are all the same so you can use the same spawn.
Now go and speak to Ragnar who will give you a necklace. Head to the island which you spoke to Asleif on. Use the bury option on the corpse to bury her.
Use one of the rocks with the burial mound to complete the quest.
