Konrad von Carstein was a mad noble from Sylvania and made Vampire by Vlad von Carstein himself. After Vlad's dead Konrad led his own Undead army into the Empire but was stopped at the Battle of Four Armies and eventually defeated in 2121 IC at the Battle of Grim Moor.
Konrad, a nobleman in Sylvania, was completely mad. He had the reputation of being a blood-mad butcher, cruel, merciless and insanely ruthless. He had cats killed for sports, burned villages because they smelled and had his mother prossecuted for giving birth to Konrad. Nonetheless, Vlad granted him the Blood Kiss, turning him into a vampire and extending his cruel rule into centuries.
Konrad fought during the Wars of the Vampire Counts under Vlad.
The vampires that had survived the siege of Altdorf fled back to Sylvania after their leader, Vlad von Carstein, was killed by Grand Theogonist Wilhelm the third. Five vampires claimed to be the heir of Vlad: Fritz, Hans, Pieter, Konrad and Mannfred von Carstein. Konrad killed one of them, Hans, in a quarrel over who was the thoughest. Having enslaved a few necromancers to do his will (he wasn't a great sorcerer of his own), he gathered an army of undead and ravaged the length and breadth of the Empire, which had not yet recovered from Vlad's incursion and was still divided as three claimants fought over who would become the new emperor. Konrad was a cruel commander and offered no surrender, slaughtering everyone who crossed his path.
In 2100 IC at the Battle of Four Armies the three claimants combined forces to fight the vampire. Konrad was driven back from the gates of Middenheim. The strife not completely forgotten, two of the claimants, Lutwik of Altdorf and the Ottilia of Talabecland ordered the assassination of each other during the fray, the third, Helmut of Marienburg was killed by Konrad.
In the spring of 2121 IC, the three claimants (their heirs) united forces once again and, combined with an army of Dwarfs, defeated Konrad at Grim Moor. The Dwarf Grufbad held Konrad down while Helmar, son of Helmut, impaled Konrad with his Runefang.
