Rikdine was a captain within the Republic Military, a male Human who participated in the Battle of Corellia amidst the broader Galactic War against the Sith Empire. Acting as a go-between for the Jedi Order and Republic's forces stationed on the planet, he played a role in organizing the arrival of Jedi reinforcements for the Jedi Knight known as the Hero of Tython—the newly appointed Supreme Commander of Jedi forces on Corellia.
By 3640 BBY, Rikdine, a male Human, had attained the rank of captain serving in the Republic Military. As the Galactic War ignited between the Galactic Republic and the Sith Empire, Rikdine was among the personnel dispatched to the Imperial-occupied world of Corellia with the objective to drive the Empire's presence from the strategically important Core World. Rikdine found himself stationed within the Blastfield Shipyards area, situated on the periphery of Coronet City, Corellia's capital. During the conflict, he functioned as the dedicated military liaison for Grand Master Satele Shan of the Jedi Order. With many Jedi fell during the initial phases of combat, Rikdine made sure that the deceased were returned to the Order's homeworld of Tython for proper burial. As the battle intensified, Shan communicated with Rikdine, informing him of the imminent arrival of Jedi reinforcements that Shan had gathered from the Outer Rim Territories as well as various other planets.
Operating from his position at the Socorro Freight building located within the Blastfield Shipyards, which was repurposed as a temporary Jedi command hub, Rikdine oversaw and managed the arrival of Jedi shuttles, guaranteeing their secure landing. When the Hero of Tython—a Jedi Knight recently designated as the Jedi Supreme Commander by the Grand Master—arrived at the building, Rikdine expressed his relief at the Knight's safe arrival and provided the Jedi with all available intelligence regarding the surviving Jedi on Corellia. While the Hero sought out those Jedi, instructing them to assemble at the Socorro Freight building, Rikdine oversaw the final transports coming from the planets Orto, Rodia, Kinyen, and Duro. Upon the Knight's return to Rikdine, the captain conveyed General Var Suthra's request for a holocall, connecting the Knight to the general in the Labor Valley sector. Following Suthra's instructions, the Outer Rim Jedi relocated to the Labor Valley, with Rikdine supervising their movement to the designated area.
Rikdine, a fair-skinned individual, possessed brown hair and green eyes, although he was largely balding by the time of the Corellia conflict. He demonstrated competence as a commander and coordinator, and he was saddened by the loss of Jedi lives during the Battle of Corellia, striving to ensure the dignified treatment and return of the fallen to their homeworld.
Rikdine was seen wearing a gray uniform indicative of his service in the Republic Military.
Rikdine's initial appearance occurred in the Jedi Knight-class mission titled "Jedi Commander" featured in Star Wars: The Old Republic, a video game launched by BioWare and LucasArts in 2011. Similar to characters in the other three Republic-class storylines set on Corellia, Rikdine also assigns the player the task of communicating with Corporal Hartke, who serves as the initial character for the Republic world arc within the Blastfield Shipyards. Progression of the class storyline to the Labor Valley is contingent upon completing the world arc mission "Blockade Runner." If the player has previously completed Hartke's mission, Rikdine will not make mention of it. Due to the ambiguity surrounding who canonically completed "Blockade Runner," this article omits any information pertaining to that mission.
