Vandran

 was a human captain and mentor of Fjord who had some connection to Uk'otoa, Fjord's patron. As an NPC, he is played by Matthew Mercer.

When Fjord pushed the yellow eyelike orb into his chest, he saw a vision of Vandren standing over a dead body. In the vision, Vandren pushed the same orb into his chest and summoned the falchion associated with Fjord's patron.

When questioned afterwards by the Mighty Nein, Fjord described the vision and mentioned Vandren as his mentor who he had not seen since sabotage sank the ship they were on.

Captain Avantika told Fjord that the one who introduced her to Uk'otoa was Vandren, and that he had wielded a sword that was just like Fjord's. She also said Vandren had an amber stone just like the one she and Fjord carried within them. She referred to the falchion as the "Sword of Fathoms."

Fjord attempted to lie to Avantika, claiming he did not have a connection to Vandren. She was able to see right through his deception.
