In the Shadow of Time is a side quest that teaches you the unforgivable curse, Imperio (optionally), and advances your connection with Sebastian and Ominis. This quest requires you to explore an abandoned tomb and overcome various challenges before confronting Sebastian and Ominis’ strained relationship.
So once you actually find the relic, you will hear about something called “A Dark Sacrifice” that will lead you to make a conflicting decision regarding whether to actually take the relic or leave it behind, for safety measures. So that leads us to the main question.
Should You Let Sebastian Take the Relic or Not in the Shadow of Time Quest in Hogwarts Legacy
A genuine cause of concern indeed, especially since the note forbids you from taking the relic. Thus you voice your concern and suggest that you should leave the relic alone. But guess what Sebastian says?
He assures you that you were meant to find this “for Anne’s sake”, as if it was all a part of some grand prophecy. He will get on your nerves, quite frequently, if I might say. And having said that, he collects the relic.
However, if you choose to agree with him and make the choice “We need that relic.”, you are basically picking his side, which would make him the happiest creature.
Final Thoughts on the Choice “Let Sebastian Take the Relic or Not in the Shadow of Time Quest in Hogwarts Legacy”
Thus needless to say, this choice does not really affect the outcome. Nevertheless, whatever you choose, Sebastian will act on his own will and collect the relic. So like most other dialogue based choices, this choice does not affect the outcome of the main storyline. The only thing that differs in either choice is just the immediate response and nothing more.
