Life after deathEdit
Helgi only exists as an innocent ghost and is unaware of the gravity of the events involving her family. Many suspected her father Hroggar was to blame for the fire, since he had run off with Alva soon after the tragedy. However, during a game of ghostly "hide and seek," Thonnir's missing wife Laelette, a vampire, is found at Helgi's exhumed coffin, thus unfolding a new chapter in the girl's story. Helgi's coffin can be found west of the house, over a rocky hill.
After killing the master vampire in his lair, Helgi appears near the exit and thanks the Dragonborn for "making her mother feel better". Then Helgi will forever disappear. There is a glitch where immediately after talking to Helgi, when about to leave the cave and engaging in conversation, she will say "Mother's calling me, it's time to go to sleep" and then she will disappear.
Helgi is referred to in Anise's Letter which can be found in the Cellar of Anise's Cabin.
"Helgi, dear, why do you hesitate? You can feel the power coursing in your blood! You have only to reach out and grasp it! Renounce that boy of yours and come, come live with me in the forest. My sister will be here soon. Together, we can form a proper coven, and your training will truly begin."
Once this letter has been retrieved, Anise will become hostile and attack, saying,
"No! No one can know my secret!"
Whether or not this is the same Helgi is not confirmed.
- Helgi's coffin and exhumed grave disappears once the quest is completed, appearing as untouched flat ground instead. They will also not be there if Laid to Rest was not started.
