Finnegrin

Castain of Shelley and of the former Sea Legs.Finnegrin was the ruthless ruler of Scumport who possessed enough power to make others, such as Elmer, fight on his behalf.[2] His signature move for keeping his subordinates afraid and loyal was to use Ocean magic to freeze the blood in a person's body, incapacitating and inflicting great pain on them all at once.[1] He would flip a coin to determine the fates of his captured enemies. If heads, he would drown them in the icy depths. If tails, then they wish it had been heads.[3]

Finnegrin was business savvy and willing to listen to the requests of others and give them a chance to impress him, regardless if the business was legal or not. However, if they failed to meet the expectations they built up in his mind, then he would see to it that it would end very badly for them.[4]

While most elves are appalled and disgusted by dark magic, Finnegrin was the opposite. He asked Callum for the spell that slew Avizandum so that he could kill Domina Profundis in order to avenge the death of his favorite pet Giant Hermit Crab and gain total dominance over the seas.[1]

Although Finnegrin could be courteous towards potential allies,[4] he was also vengeful and harbored a deep grudge for anyone who crossed him. He claimed his greatest desire was to achieve true freedom as a pirate, but in reality, his greatest desire was to control all of the seas and everyone around him to maintain his power. However, being born with the Ocean arcanum, he knew deep down that he would never truly be able to control everything, and that secretly terrified him
