Marius LePual

 is a half-elf tramp-turned-sailor and (presumably) boatswain of the Nein Heroez. As an NPC, Marius is played by Matthew Mercer.

Appearance
Marius is a skinny, handsome, half-elven man with blonde hair cut short on the sides and a curl of hair that flops down on his forehead.

Personality
Marius is a roguish and opportunistic individual with a reputation for landing himself in trouble. He told the Mighty Nein that he is a pretty talented cook. He is also very concerned about his appearance, being extremely distressed when Beau ruins his expensive shirt sleeves, and is self-conscious about his hair and teeth.

Marius LePual was the person mentioned in the letter written by Avantika that the Mighty Nein found in Lorenzo's Bag of Holding, to whom the Cloven Crystal was to be delivered.

Marius attempted to meet with the crew and captain of The Mist, but his meeting was interrupted when the crew attacked the Mighty Nein, who proceeded to kill most of the crew, set sail, and kidnap Marius. During this event, Beauregard choked him with her quarterstaff, Nott tied him up, Yasha later tied him to the mast, and the Mighty Nein said they probably wouldn't kill him. Marius took those odds over being killed.

Marius remained tied to the mast for a while, falling asleep there. He was woken up by Beau and Fjord, who questioned him and learned that he never intended to go on the ship, and just wanted to meet with the captain to give back the money he was hired with, since he was unable to retrieve the Cloven Crystal. Marius was later freed and allowed to walk within the ship, though Fjord let him know that he was stuck with them.

Marius stayed aboard the ship (now known as The Mistake) while the Mighty Nein returned to Nicodranas to hire a crew before setting sail again. He had a conversation with Caduceus, asking whether he would be released; he wondered if Caduceus would be willing to leave alongside him. Although Caduceus wouldn't commit to running away, he assured Marius he could help him leave if it came to that.

The Balleater returned to Nicodranas. The Mighty Nein made Orly Skiffback the new captain and set off to Felderwin. Marius stayed with the ship as part of Orly's crew, apparently as his boatswain ("bo'sun").

Marius was on the Balleater eating a sausage when the Mighty Nein visited it in Nicodranas harbor. He had grown about as much beard as a half-elf can muster and adopted a faux-weathered fashion look. Orly Skiffback said they were working on him, and he figured it would take about three more years.

Orly Skiffback
Orly and Marius have been friends since before they met the Mighty Nein. On occasion, when Marius needed a place to stay, Orly would let him crash on his couch. When first questioned by the Mighty Nein, Orly deliberately withheld information to protect Marius. While on Darktow, Orly and Marius were protective of the rest of the Nein's hired crew. Marius was distressed when Orly was killed in battle.

The Mighty Nein
The Mighty Nein and Marius have a troubled history. Their relationship began when the Mighty Nein kidnapped Marius in. Afterwards, Marius stayed on as a part of their crew, and sailed with the party across the Lucidian Ocean. Along with Orly, Gallan, and Shelda, Marius is one of the permanent crewmembers who looks after the Mighty Nein's ships while they are away on other business. While intimidated by the Nein, Marius is nonetheless loyal to them. He was initially happy to see the Mighty Nein return to Nicodranas, and aided them in defending the Balleater against minions of Uk'otoa in.

The Mighty Nein (and their players) have a running gag about how useless Marius is, and frequently blame him when things go wrong. Fjord, Yasha, and Beauregard in particular have implied that Marius should prove himself to them by committing murder.

 * "I don't ask questions of those who are, you know, a full foot and a half taller than me and can probably wipe the floor with me. I just nod, take my money and do the job."
