Ophiscan Duth

 was a dwarven crewmember on board the Squall-Eater, serving as the master gunner under Captain Avantika. As an NPC, Fiskin was played by Matthew Mercer.

Appearance
Fiskin was a dwarven man with a puffy, red chinstrap beard.

Personality
Fiskin didn't seem to have much of a problem with the Mighty Nein goofing around with black powder on the gun deck and actually found it pretty funny, at least until Caleb showed up. Fiskin also showed himself to be surprisingly patient when teaching Nott how to fire a cannon.

After her initial training, Fiskin supervised Nott during the time she was attempting to steal black powder, and is likely responsible for her stealing black pepper instead.

Fiskin was present for the fierce battle between the crew of the Squall-Eater and The Mighty Nein. It can be assumed Fiskin was killed in battle when Caleb cast Fireball as the only known survivors apprehended in the aftermath were Bouldergut, Jeremiah, Ipess and an unnamed human crewmate.
