|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. In 1722, Loftur was presumed lost at sea. The Rauoskinna washed ashore and was returned to the tomb.  
In truth, Loftur did not die. Instead, he discovered the secret of immortality.  However, he never found the Rauoskinna. He kept tabs on Egon Spengler ever since he first searched for the Rauoskinna in his college years.  He came to believe the Ghostbusters were the only way he could bypass the Rauoskinna's defenses and came up with a plan to enlist their services without them knowing it.  Loftur secured the Ghostbusters' assistance slyly through his proxy Erland Vinter.  Loftur was not pleased with Vinter's results and decided to approach Egon directly. Just as the Ghostbusters concluded their case in Ireland, Loftur went to Egon's Apartment. He presented a story that while he was at Ray's Occult Books, Eduardo Rivera informed him Egon was looking for a copy of The Johansen Argument. Egon realized Eduardo didn't have his address and asked how he found him. Loftur eyes glowed red and he cryptically answered "magic." Egon fired his Psychokinetic Defibrillator point blank in Loftur's face. Since Loftur was not possessed, the Defibrillator had no affect on him at all. Loftur sent Egon flying across his apartment. Loftur formally introduced himself and verified reports of his death in 1722 were false. Egon wasn't buying that Loftur would wait to long to show himself and released the Gulper Ghost from the Paranormal Containment Research Tank. The ghost flew through Loftur and coated him in slime. Loftur was mostly disgusted. Egon called him a coward for trying to manipulate the Ghostbusters into locating the book. Loftur admitted he should have been direct but felt threatened. He went so much as to claim they were kindred spirits then asked Egon to help him locate the Rauoskinna with the promise of learning so much from owning the Devil. Egon refused. Loftur decided to give Egon the chance to rethink his answer and atomized him.
Kaia May went to the Firehouse and revealed to them that Vinter served Loftur. She then passed along their new demand, find the Rauoskinna for them and Egon would be restored. She gave them a list of possible locations of the key and map to the book. Before she left, Kaia admitted she didn't think neither Vinter or Loftur could be trusted and advised them to destroy the book when they found it.
Loftur was a sorcerer according to legend. He is also immortal and has managed to live for almost 300 years. One magic spell used on Egon appeared to resemble telekinesis while another atomized Egon through some form of accelerated cellular dispersal.
- 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.
- In the what came before! page of Ghostbusters International #8, the spelling of Loftur's last name is poked fun at.
