|Specifics: This is for Ghostbusters International|
In the 1700s, nearly 200 years after the death of Gottskalk Nikulausson, Loftur allegedly deciphered the clues hidden by a secret society tied to the Church of Holar and discovered Gottskalk's hidden tomb. He removed the Rauoskinna from the tomb and attempted to leave Iceland with it. He was attacked by the Spirits of the Ocean due in part to a spell of protection cast on the book by Gottskalk. Loftur was presumed lost at sea. The Rauoskinna washed ashore and was returned to the tomb. 
Loftur was a sorcerer according to legend.
- On page 4 of Ghostbusters International #5, panel 2, one of the words written on the board is "Staðastaður." In the folktale about Loftur's death, he felt like he would die on a certain Sunday after an encounter with Gottskalk's ghost. His friends advised him to see a priest in Staðastaður. He stayed with him until a Sunday but after the priest went to perform last rites, Loftur went out on a fishing boat and was pulled underwater.
- On page 5 of Ghostbusters International #5, Loftur's last name is misspelled a "B" instead of a "Þ" as well as other minor lettering issues with Icelandic terms and names.
- On page 5 of Ghostbusters International #5, in panel 4, the rune that Loftur finds is the Ægishjálmur (or Helm of Awe), an Icelandic magical stave said to induce fear and to protect against abuse of power.
- The story of Loftur's search for the book and being dragged underwater from his fishing boat was the subject of actual legend. Some claim it was suicide instead. He was never heard of after 1722 according to record.

Egon Spengler says: "The clues were deciphered nearly 200 years after Nikulausson's death by the sorcerer Loftur Þorsteinsson, who found the grave, and the book... but it was attacked by the Spirits of Ocean itself when he tried to leave Iceland with it."
- ↑ Egon Spengler (2016). IDW Comics- "Ghostbusters International #5" (2016) (Comic p.5). Egon Spengler says: "Loftur's body was never recovered - hardly unusual considering it was lost at sea during the 1700s. The book was said to have washed up onshore later, before being returned to Nikulausson's hidden tomb."
