Mikaele Salesa is a fence who deals heavily in paranormal artefacts (though no books), among regular ones as well. He was once one of Jurgen Leitner's assistants, and took his client list when he departed the job, which gave him many contacts dealing in objects with supernatural artefacts. Some of the "more bizarre" artefacts in The Magnus Institute's artefact Storage were purchased from him, and he refers to them as "one of his most stable customers".
The only known description of Mikaele Salesa is "a big Samoan guy with close-cropped hair".
Pre-1994 - Mikaele Salesa quits his job as an assistant in The Library of Jurgen Leitner, "helping himself" to Leitner's client list.
Autumn 1999: A man referred to as "Cook" working for Salesa aboard his ship discovers an antique meat grinder among the cargo, and Salesa sells it to him. After the ensuing meaty adventure, Salesa ends up killing Cook in self-defence and making a rule for himself that only he is allowed to inspect his cargo.
Spring 2010 - Dr. Neil Thompson sells an antique syringe, allegedly belonging to John Snow, to Mikaele Salesa.
pre-January 2007: Mikaele Salesa sells a Slaughter artefact to the Institute which something then goes wrong with. Despite insisting that he isn't liable, Salesa appreciates them keeping it quiet, and agrees to give them a statement (not his first), deciding on the meat grinder incident.
Early 2011 - Lee Rentoul puts a curse on Paul Noriega after unwillingly spending 5 years in prison for him with the help of a old woman named Angela from Bexley. After Rentoul kills Noriega (at a meeting with Mikaele Salesa), the curse passes to him, causing him to progressively lose parts of his body.
May 2012 - Andre Ramao, having bought a Chinese urn from Mikaele Salesa, begins inexplicably losing items, with no record of them ever having existed. When Salesa is consulted about the urn, he tells Ramao that "[I] don't remember owning it, which means it belongs to you". Over several months, Ramao becomes progressively more obsessed with the urn, until he falls asleep in front of it, when all the items are returned. After fleeing pale, filthy hands pushing themselves out of the urn, Andre's husband disappears.
2014- One of Salaesa's crew members is killed by a carpet influenced by the Spiral, and he throws both the carpet and the man overboard.
After the conclusion of that voyage, Salaesa announces his retirement to the crew of the Dorian. He also says that before he retires, he wants to go one one last voyage, and any crew member who wants to join is welcome, though it will be very dangerous. The voyage is completed successfully.
Back on land, Salaesa insists on throwing a party, but an explosion goes off that night while he delivers the artefact, killing Salaesa and the captain of the Dorian, who dies from the shrapnel a short while later.
