Sevrin was noted for his work in the use of technology to maximize the value of conquered worlds to the Empire. In the 2260s, at the height of his scientific career, he was appointed science minister in the cabinet of Emperor John Gill. Throughout his tenure, Sevrin revolutionized the ways that subjugated worlds could be completely stripped of all resources through technology, affording him good standing with both his emperor and the Imperial Senate of the Terran Empire.
In appearance, it was noted that Sevrin bore a striking resemblance to another cabinet member, Melakon. Despite their facial similarities, it was easy to tell the men apart due to Melakon's Human-like Ekosian appearance and Sevrin's distinctive Tiburon ears and baldness.
