Dirk Manleigh was the Sentinel Faction Rep in Nimbus Station. When players first arrived in Nimbus Station, Nexus Jay sent them to speak to the four faction representatives, including Dirk Manleigh, in order to receive faction badges and join Nexus Force. Dirk Manleigh sent players to begin their battles by searching for the Sentinel Agent Melodie Foxtrot, who will gives players the Sentinel Badge. Dirk Manleigh was removed in the Power of the Nexus Force update. His role has since been succeeded by Xeno Blueblade.
