Speak to Sebastian

Sebastian and Ominis will be in the northwest corner of The Great Hall arguing pretty loudly about the dark arts. The quickest way there is to fast travel to The Great Hall Floo Flame location. You can listen to their short conversation, then speak with Sebastian to get the details. If pressed, Sebastian will disclose to you the tragic relationship that Ominis has with his family and their links to dark magic, and the Crucio Curse.

What’s more, Ominis learned from his family that there is a hidden ‘scriptorium’ that belonged to Salazar Slytherin in Hogwarts Castle. Sebastian is convinced that there might be information in this chamber to help his sister, but Ominis, understandably, wants nothing to do with the black arts or Salazar. Sebastian says he will try to persuade Ominis, and reach out to you via owl in the immediate future.
