Once you get far enough in the main story of Hogwarts Legacy, you will be able to start doing companionship quests. These quests revolve around your friends, but none is more interesting than Sebastian’s questline, as it allows you to learn the three unforgivable curses. The guide below goes over how to start Sebatian’s quest line and complete his first companionship quest.
How to Start and Complete In The Shadow of The Bloodline in Hogwarts Legacy
To start this quest, you will need to have completed In The Shadow Of The Estate, a main story quest. Once you do, you will need to meet Sebastian in the Great Hall. When you enter the room, take a right, and you will find Sebastian arguing with Ominis about using the dark arts. Once Ominis departs, speak with Sebastian, he will ask for your feedback on the topic.
At this point in his storyline, your dialogue choices won’t affect his main quest. Keep in mind that there are several points during the rest of Sebastian’s quest line where your answers will impact the ending.
