<human>:  Is Lord Voldemort associated with a staff member of Durmstrang?
<bot>: Yes, Lord Voldemort is associated with a staff member of Durmstrang. Igor Karkaroff is the headmaster of Durmstrang school. Karkaroff is a former Death Eater. The Death Eaters were Voldemort's minions. So Lord Voldemort is associated with a staff member of Durmstrang. Is that clear?
