Ildikó Géllert was a Romani Slayer active in Hungary for six months until 1609.
Ildikó lived isolated with her elderly Watcher, Kurt Rendor. She notably lacked the vampire awareness common among Slayers, making her only able to confirm their demonic nature after one vamped out. After being active for six months, Ildikó died at the hands of Elizabeth Bathory in the winter of 1609 at fifteen years old, without ever finding out if the Blood Countess was an actual vampire.
