Born as Xavier de Calais, Xaviar was Embraced in his native France during the Hundred Years' War. Abandoned by his sire after the Embrace, Xaviar traveled north to Scandanavia, where he remained a solitary monster-hunter for several decades. Eventually, he traveled to Germany's Black Forest, where he became a renowned Lupine hunter. During this time, he first became acquainted with the Camarilla and the Masquerade.
After some time in Kindred society, Xaviar's wanderlust led him to the Middle East and, from there, Africa. At the dawn of the 18th century, he traveled to North America, where he tracked down and destroyed the Gangrel Justicar Elijah, who had succumbed to his Beast. When he presented the Conclave of 1704 with evidence of this deed, he was made an Archon on the spot, and was appointed to be the clan's new Justicar at the next Conclave, seven years later. He served his clan as a Justicar intermittently for centuries. Xaviar's base of operations is in New Orleans, where he hosts a Conclave every three years.
A year later (or, alternately, shortly before the Conclave in 1998), Xaviar led a war party of Gangrel in an assault on a bizarre creature that slaughtered and deformed nearly all of the Kindred it fought. Xaviar came to believe that the creature was an Antediluvian; when he brought his concerns to the Camarilla, he was rebuffed, with the Camarilla's leadership repeating their claim that the Antediluvians were merely a legend. Incensed, Xaviar announced that his clan was, as of that point, no longer a part of the Camarilla.
Xaviar later unsuccessfully attempted to sway the Camarilla's Gangrel warlord Karsh to his side by reminding him of the clan's history and of the portents that their legends held for their future. Later, the two came into conflict when Xaviar backed the rogue Brujah Archon Theo Bell in his investigation into a network of Kindred slave traders that was targeting the now-solitary Gangrel clan. Together, Xaviar and Bell defeated and staked Karsh, and threw him bodily into the Atlantic Ocean. Xaviar soon gathered a number of prominent Gangrel (including the Chicago primogen Inyanga and Prince Mark Decker of Milwaukee) to ally against the slavers' diabolist Brujah puppet-masters. This Gangrel force backed Xaviar and Bell in their assault on the slavers' main compound. Although the slavers were broken and their leaders destroyed, a True Brujah ancient infernalist was able to kill Xaviar using Baalfire and ripping out his heart and eating it at the culmination of the battle.
