In the Shadow of Discovery is Sebastian Sallow's third relationship quest in Hogwarts Legacy.
This quest does not count towards the Complete Side/Relationship Quests, so XP is not earned for completing it.
Objectives[]
"Sebastian sent me an owl saying he found something interesting in the book from the Scriptorium and he wants to discuss it in the Undercroft."
- Speak with Sebastian in the Undercroft
"Unbeknownst to Sebastian and me, Ominis arrived in the Undercroft and overheard our entire conversation. Ominis is furious. Perhaps I should try to reason with him."
- Talk with Ominis after he finishes with Sebastian
Conclusion[]
"Salazar Slytherin's spellbook contains references to a lost relic which, from what Sebastian can tell, grants the holder the power to reverse Dark Magic curses. Sebastian's determined to search for this relic but doesn't want Ominis involved. Ominis overheard everything and warned against searching for such a relic. I doubt Sebastian will leave something this promising unexplored."
