Aubrin Bel-Lattain is a citizen of the Imperial Combine, who may have been a permanent resident on Serrofus Major.
It can be inferred from his name that he is a Raised citizen, with enhanced social and political privileges.
While present on the surface of Serrofus Major, enacting elements of Voice's plan to gain control of MAGA assets, Herik Pammon was stopped by an infantry patrol and challenged to provide his identity. He lied, and claimed to be Aubrin Bel-Lattain (→TRD).
The ruse did not last long, since Pammon aroused suspicion when it became obvious he did not know in which area of the planet someone of Bel-Lattain's status would live. One of the soldiers was then able to download an image of Bel-Lattain, which showed clearly that Pammon was lying (→TRD).
No further information is recorded regarding Aubrin Bel-Lattain.
