After discovering Salazar Slytherin's spellbook, Sebastian calls you to the underground to discuss how to go forward.

  • Requirements - Suggested Level 17

After completing Professor Weasley's Assignment, Sebastian's In the Shadow of Time quest will be available. You will visit the Feldcroft Catacomb with Sebastian to discover an ancient relic. You will need to find a way through the bone barricade during this quest and eventually come across the relic. However, Ominis shows up at the catacomb, and here you'll need to choose a side between him and Sebastian. Your character ends up convincing Ominis, and this is where you'll learn how to cast the Imperio spell to use it on Ominis.

In the Shadow of Distance

Sebastian calls you to the undercroft during In the Shadow of the Distance. He is more obsessed than ever with figuring out the relic's secrets and believes that dark magic will help cure Anne. Sebastian also sends a crest to meet up with Anne secretly at the spot.

In the Shadow of the Mine

  • Required Level - 22

Sebastian asks you to meet at the Overlook Mine in Upper Hogsfield to investigate the goblin camp there. This is where you will come up against several Goblin Loyalists and defeat them to get inside the Overlook Mine. Inside the mine, you need to investigate the rune symbol, and eventually, you will discover the second canvas piece of Isidora's triptych. After finding the item, you and Sebastian will return to the undercroft to discover Ranrok's mine located at Marunweem Lake.

In the Shadow of the Mountain

During In the Shadow of the Mountain, you must find the third canvas piece to complete Isidora's triptych.

You will find plenty of Goblin enemies like Loyalist Warriors, Rangers, and Loyalist Assassins in the way, eliminate them quickly, and move ahead.

After entering the Cavern, you need to search for the Runes. This is where you and Sebastian will face a giant Troll. While exploring the Cavern, you will discover certain manuscripts from Isidora's journal. The third and final triptych segment is located in the room with the cauldron. Here you'll find another journal parchment and an exit leading to the undercroft.

In the Shadow of Hope

Sebastian wants to speak to Anne without Solomon knowing and invites you to listen to them outside Feldcroft. Travel to the region and listen to what Sebastian has to say. He speaks about the dark sacrifice mentioned in the relic he found at Feldcroft Catacomb. Sebastian intends to revisit the catacomb to discover the relic's true secret and wishes for Anne and Ominis to be there. Before visiting the catacomb, he will send you an Owl, keep an eye out in the mail as this will start the next quest.

  • Requirements - Suggested Level 28

After completing Lodgok's Loyalty, Ominis will send you an Owl saying he is concerned about Sebastian. You both will visit the Feldcroft Catacomb to see what Sebastian is doing. You must fight through the inferius and repair the catacomb bridge to reach Sebastian. He discovers a way to use the dark magic of the Relic to cure Anne, but Uncle Solomon intervenes and destroys the relic.

A fight ensues with Sebastian and your character fighting Solomon Sallow. After a while, Sebastian uses Avada Kedavra to kill Solomon. Anne reaches the catacomb too late and destroys Salazar Slytherin's spellbook before disappearing from the area. Sebastian exits the catacomb, and you need to follow him. After this, he teaches you Avada Kedavra, the killing curse. This is one of the most potent spells in the game but has a long recharge time.

In the Shadow Fate

Sebastian meets you and Ominis in the undercroft, where he learns that Anne had to bury Uncle Solomon alone. Ominis speaks about turning Sebastian in, and this is where you get a choice. You can choose to hand over Sebastian or protect him by convincing Ominis.

In the Shadow Friendship

After the Final Repository mission, Professor Weasley gives a speech regarding Professor Figg's death in the main hall. Once that's done, you must visit and interact with Sebastian at the undercroft. This is where Sebastian speaks about Anne being alone without her brother and that he repents for his actions.

Exploring dark magic wasn't his intention, as he only wanted to find a cure for Anne. Speaking to him in the undercroft completes this final relationship quest in Hogwarts Legacy Sebastian Questline.
