Argelian was a Romulan military officer who served as navigator aboard the ChR Raptor in the 2260s. During a confrontation with the USS Enterprise in 2267, Argelian urged Commander S'Talon to go against orders from the Praetor and attack the Enterprise. However, when it came to challenging S'Talon outright, Argelian backed down. (TOS novel: Web of the Romulans).
