The Coordinator of Acquisitions for a low-key corporation on Aaru IV, Carter Reiser appeared to most who met him to be little more than a snivelling backwater information merchant. However, his true nature was certainly much more devious. Reiser curated a carefully manufactured identity for himself, whereby he ensured that those around him underestimated him or at the very least assumed they were smarter and better informed than he was.

In reality, however, Reiser coordinated a network of underworld contacts for the Zarbomba corporation, and kept his true involvement in their affairs a secret. When he became an unwitting participant in the search for Uro Gruul’s Gamorrean minion Gardok, he was later discovered with several rare Stybian crystals on his person—the famously rare mineral indescribium. Whilst the Crew of the Behemoth coerced Reiser to offer up information he possessed on the White Scar Pirate Cult—whom he professed to know nothing about—he nevertheless obfuscated his true intent: reconaissance on behalf of Zarbomba.

Kept prisoner upon the Behemoth for some time, a dishevelled Reiser made his escape when the ship was docked at a supposedly abandoned mining base within the asteroid field surrounding Stybius. Pursued by the Crew, he was once again recaptured for interrogation, but not before he could warn the White Scars, hoping they might intervene on his behalf. During the confrontation on the mining base, Reiser disappeared and presumably returned to Aaru IV in order to report his findings to his corporate masters.
