Sabian

 is a former crewmate of Fjord.

Background
Sabian was the one responsible for sabotaging the ship Fjord worked on. Fjord walked in on Sabien lighting a fuse, but before he could react Sabian wounded him with throwing daggers, ran to the deck of the ship and jumped into the ocean. After surviving the explosion Fjord returned to one of his contacts and learned that Sabian had also survived.

Captain Adella tells Fjord that Sabian has recently been working with a shady merchant named Cadmus Leeland in Nicodranas. Leeland's ship is named the Widow's Embrace.

Relationships
Fjord told the Mighty Nein he's known Sabian for many years, and they grew up together. Despite this, Fjord does not seem to have had a good opinion of Sabian even before the Tide's Breath explosion.
