Alexander Stern
Stern was appointed Regent of the Prague Chantry in 2013 when the previous Regent vacated the position for reasons unknown.
Initially, Stern was sent from Vienna to investigate the reasons behind the former Prague Regent Ildephonsus Steinhebel's treason but his duties kept piling up since his superiors were pleased with his results. Stern searched Prague and secured Steinhebel's belongings along with rooting the remains of his influence and experiments in the city. Some of the Prague Kindred say that during this time, you could tell where Stern was by the rising smoke from burning houses.
After his investigations in Prague in 2013, Stern returned to Austria where he conducted experiments in the village of Wolfenstein but promptly returned to Prague. It was around this time he was appointed the new Regent. It is rumoured that Alexander actually lost in status among the House and Clan by his new posting and that Regency wasn't really a promotion for him and that he only accepted because the House and Clan Tremere needed a capable Prague Regent.
Alexander is a respected figure in the Prague Camarilla although some scoff at his strict interpretation of the Traditions and frequent requests for employing extreme measures against transgressions against the Camarilla.
Alexander isn't a frequent visitor at the Elysium. He tends to the needs of the House and Clan instead, as well as continuing with his research. He supposedly nearly destroyed the Prague Chantry on several occasions when rituals led by him had unforeseen "side effects" and the dungeons beneath the Chantry house include at least one very powerful artifact forged by powerful mortal mages.
In 2015 Stern was appointed Primogen after his predecessor Václav Gauss who resigned on the post.
