It looks like she was a Worm Cultist who was mauled to death by sabre cats. You see Nordahl's body; he appears to have been clawed by a human. Activate the kindling, and take both kindlings. Nordahl's summoning circle is to the left of the tent where you found the geode. Stay alert between Riften and Greenwall. If you do complete the quest, the doors to the Forelhost Crypts subsequently remain unlocked, so you can return to the summit if you missed the Skyshard. You tell her you'll gather kindling for her, and she tells you you'll need to stay close to the fires to survive and warns you about the sabre cats. Reward The clue in the Journal Achievements list simply states "A walk above the clouds" without indicating that it is the name of a quest which the player must undertake -- not just a description of what their character must do to find it, or how the player might recognize its proximity to their character. Note: You need to do this quest for Skyshard #8. She thinks the cult left their leader (along with the shard) on the top of the mountain. The order is: East, West, North, South.
