Vloun was an Orion and president of the Botchok Planetary Congress after the second Klingon occupation of the Orion Colonies during the Four Years War.

On stardate 1/9808.15, Vloun and Commissioner Dzwonkowski of the Federation's Rigel Demilitarized Zone Commission signed the Orion Emigration Act, which required the registration of all Orions in Federation space. (FASA RPG module: The Orions: Book of Common Knowledge)

The length of Vloun's reign is unknown, but he may have also been in power during at least the end of the Four Years War and the formation of the Orion Neutrality Area, and the later abolition of Orion slavery.
