Sabian

 is a former crewmate of Fjord.

Appearance
Sabian was described by Fjord as a dark skinned half-elf man.

Personality
Due to Sabian's general nature, he and Fjord didn't get along with each other well.

Background
Sabian was the one responsible for sabotaging the ship Fjord worked on. Fjord walked in on Sabian 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 told Fjord that Sabian had recently been working with a shady merchant named Cadmus Leeland in Nicodranas. Leeland's ship was named the Widow's Embrace.

Campaign 2: The Mighty Nein
 Fjord talked to Mollymauk briefly about the explosion of the Tide's Breath and the possible connections to his new falchion.

 While the group spent some downtime in Zadash, Fjord traveled to Trostenwald by himself to see if anyone had heard of Sabian or of the Tide's Breath. After returning to Zadash, Fjord confided in the rest of the group about Vandran and Sabian, and their possible connections to his sword.

 Fjord introduced himself to Captain Adella and asked if she knew anyone by the name of Sabian. She told Fjord that Sabian had recently been working with a shady merchant named Cadmus Leeland in Nicodranas. Leeland's ship was named the Widow's Embrace.

 Before leaving Rumblecusp, Fjord hired Kotho to provide him information on Sabian's current location.

 After speaking to Fjord, Jester used Sending to contact Kotho, who then revealed Sabian had been found and is currently residing on Darktow Isle.

Fjord
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. It is unknown how Sabian feels about Fjord.
