In the Shadow of the Mountain is the forty-second main quest in Hogwarts Legacy. This walkthrough will guide you through all objectives of the In the Shadow of the Mountain Main Mission.
Requirement: having completed Professor Howin’s Assignment (Bombarda), Level 24
Reward: 260 XP
Quest Info: Sebastian discovered more of Ranrok’s Loyalists swarming around another cavern. We decided to fight our way past them and find out what they were looking for. In our search we discovered more runes like the ones on the note from the triptych. We then battled a troll and a nasty infestation of spiders before finding the final piece to the triptych and another passageway back to the Undercroft. We returned and placed the final canvas in the triptych, unlocking a Pensieve memory. We watched it and learned that ancient magic has healing potential. Sebastian believes we can use this power to cure Anne.

Starting Location: In the Shadow of the Mountain
We’ve learned Bombarda, the Exploding Charm, which should allow us to get through the mountain and reach the southern regions. There, we must meet with Sebastian.
Meet Sebastian Along the Coast
In order to access the southern regions, you need to head through a mine. You can’t fly or walk there, the only way is through a mine. Refer to the screenshots below to find the entrance.
You’ll eventually head back outside and be able to fly again. Once you can, proceed to the quest marker and talk to Sebastian.
Travel Up the Switchbacks
Press 
to activate your Charmed Compass. This will reveal a golden wisp trail that you can follow to your destination. Once reached, prepare for an enemy encounter.
Defeat All the Enemies
Now clear the area.
Continue Up the Mountain
Loot the area and then press again to reveal the path. Shortly before your destination marker, on the hill you ran up on, is a chest in a cave behind some Devil’s Snare.
Defeat the Guards
Now clear the area again.
Enter the Caverns
Loot the area, making sure you activate the Tower Tunnel floo flame here, then enter the caverns at the quest marker.
Search for Runes
Continue down the tunnels and kill the spiders. Loot the area, including the area behind a Bombarda wall for a chest, then continue down the slope. In the next area, defeat some more spiders, loot the area and continue on. Go up the staircase, burn the spider web, then blow up the wall with Bombarda.
Then, continue down the spider egg tunnel.
Defeat All of the Enemies
Now kill some more spiders in the arena.
Unlock the Rune Door
Now loot the area, including the spider nest where the two Matriarchs came rushing from. Then, face the door and cast Confringo at the spider web covering the rune switch right of the door. Then, hit the one behind you and the two by the door.
Search for the Triptych Segment
Go through the door and you’ll find Isidora’s Journal Entry 4/7 in an open chest in front of you, then continue on and you’ll have to fight a mountain troll.
Defeat the Troll
Now defeat the troll and spiders.
Search for the Triptych Segment
Now resume your search for the segment. Loot the area, including the small room behind the wooden barricade. In there ignite the bowl by the statue to reveal a small chest. Now return to the main room and use Reparo on the shambled stairs.
Climb up the stairs and loot the next room, including Isidora’s Journal Entry 5/7, then move the crate by the cracked wall to be able to climb it.
Climb up the stairs on the right and loot the floor, then go back down and climb up the stairs on the left. Now continue to the next few quest markers, there’s only one way to go, you can’t get lost. Inside the new room is Isidora’s Journal Entry 6/7 on a table.
Loot the room, including igniting the bowl by the statue to reveal a chest, then use Bombarda on the wall. Go up the slope, jump over the gap, grab the chest from the alcove on the right, then continue on.
Unlock the Rune Door
In the next room are two more rune switches, with the third hidden behind a Bombarda wall next to the door. Hit all three and continue through the door.
Investigate the Chamber
Inside the new room will be the final piece of Isidora’s Journal 7/7 on a table. Now go up the stairs and immediately turn around to the left and go up the ledge to find some loot, then pick up the final piece of the triptych on the table.
Use the Magic Passageway
Now proceed to the crystallized door to return to the Undercroft.
Place the Canvas into the Triptych
Now approach the triptych and place the last piece of the canvas inside it.
This finishes In the Shadow of the Mountain in Hogwarts Legacy.
