Ismelda Murk was a witch who began attending Hogwarts School of Witchcraft and Wizardry in 1984 and was sorted into Slytherin.[3]


Hogwarts years (1984–1991)

Third year

Ismelda took at least Care of Magical Creatures as an elective.[4]

During the 1986–1987 school year, she, along with fellow Slytherin Barnaby Lee, joined Merula Snyde on her search for the Cursed Vaults. When Barnaby asked his associates' opinion on what the next Cursed Vault could contain, Ismelda hoped it to be "something that could bring the Dark Lord back".[3]

Ismelda accompanied Merula to confront Jacob's sibling, Tulip Karasu, Barnaby, and another of their friends at the entrance of the Restricted Section, hoping to beat them to get into the next Cursed Vault first. When Jacob's sibling beat Merula over a fair duel, Ismelda fired Everte Statum out of the blue, which would have hit Jacob's sibling had Barnaby not jumped out to take the hit. Ismelda showed no remorse about harming her former ally, and when Barnaby refused to back down, she stated he could suffer with his new friends. Both Ismelda and Merula were then held back by Barnaby while the others entered the Restricted Section to figure out how to gain entry to the next vault.[5]

Fourth year

Fifth year

Personality and traits

Ismelda was an unbelievably cruel witch, saying that she "will cast the killing curse on the first Gryffindor she sees,"[6] or coming up with the idea to torture Jacob's sibling with the Cruciatus Curse in order to obtain information about the Cursed Vaults.[7] She was overheard telling Merula Snyde that she once had a jar of Muggle blood that dried out,[6] and gleefully voiced her hope that she would see Professor Silvanus Kettleburn "lose his other eye this year."[8] It is unknown, however, how many of these sentiments are her actual opinions or feelings, or if she says it merely for shock value.

She also appeared to sympathise with the ideals of Lord Voldemort.


  • Diary: In the side questin Year 3, her diary was aired out, revealing that she has a crush on Barnaby Lee.

Magical abilities and skills

  • History of Magic: Before the O.W.L. for the subject, Ismelda had shown her expertise in the subject due a study session with Jacob's sibling and Badeea Ali. Despite falling asleep in lessons like many others, she falls asleep due to her already knowing the subject so well, which matches her love for blood and gore.


Ismelda is a name of German or Germanic[9] origin, meaning "she who battles with sword."[10]

Murk is an Americanized or Germanised[11] spelling of the following, with the majority of them meaning "dark:" Old English mirce, Proto-Germanic *merkuz, and Proto-Indo-European *merg-. It also cognate with various languages with the meaning of "dark," including Danish and Norwegian mørk, Swedish mörk, and Icelandic myrkur.[12]
