Crest of Heroes is a side quest in the first region of Assassin's Creed Valhalla, Ryugjafylke, in which you need to find the young girl Biel's Crest.
Quest start
After you go around your camp in Fornburg, go to the blue marker in the northeast of the map. Biel sits on the banks of the river in front of the waterfall. Talk to her to find out that she has lost the comb. The two men are already busy looking for their combs, because the girl will spend the evening with whoever finds him.
Find the comb
Don't be confused by the person looking for the ridge above the waterfall. You can read Biel's note on the wooden bench for advice. Then jump into the water and swim towards the waterfall. Dive at the waterfall and look for the deepest point under the water. Use Odin's Sight to see better underwater.
Take the moose antler comb at the deepest point and give it to the girl. In addition to the skill points earned, you can now spend time with Biel. Your decisions have no important consequences.
