Ainkurn
Ainkurn is a vampiric artifact, the legendary "sister sword" of the Sword of Dracula. It's a kilij blade of Turkish manufacture, and like the Sword of Dracula, was created with the assistance of Durga Syn. It was said to drain the blood of anyone it struck.

At some point it had been taken by Teutonic Knights and kept in their Vienna base, displayed on a stand before a large mural displaying its use, apparently by a Crusader against a Muslim.
Overview
Certain tales attribute the Ainkurn sword with the destruction of Methuselahs, single-handed victories over ravenous Lupines, and even travel into the realms of the dead. Little corroborates the power of the Ainkurn sword reliably – its prowess is often demonstrated in tales of wonder and horror rather than in documented accounts. Whatever the case, the Ainkurn sword is reputed to be just as powerful as that of Dracula's – and perhaps more so, although current bearer Christof Romuald believes it is a mere shadow of the original.
