Sealed History is the Forsaken Dominion main quest that follows Seeking the Sage in Dragon’s Dogma 2’s Dark Arisen expansion. You march north with Wash and the commission soldiers, fight through the Mountain Stronghold and open its inner gate. Then you continue on your own to an underground archive where Polyeidus wants to read the old records. The quest gives no reward when it ends, but it opens The Castle in the Ice.
Quick answer: Talk to Wash at Rivercave Campground, rescue Amos, pull the stone lever behind the stronghold’s small window, reach the Sealed Study, wait one in-game day, then speak to Polyeidus again.
How Sealed History starts
You don’t need to find a quest-giver. Sealed History begins automatically once Seeking the Sage is done, which means all three sage riddles are solved and you have spoken with Polyeidus at his tent in the Norgandian Settlement. A banner reading “Sealed History / Priority Quest Set Automatically” confirms it. Polyeidus then sends you to meet the Vermund commission soldiers at Rivercave Campground.

Most of the quest takes place in the cold, and much of it involves combat, so pack the following before you leave:
- Lantern Oil. The study and the grotto near it are underground. If you see “Out of Lantern Oil,” refill from Items using “Add Oil.”
- Curatives, plus at least one Wakestone for the large fights on the way.
- Lightning skills on a pawn. Several of the large enemies here are weak to lightning.
- An Eternal Ferrystone or regular Ferrystones for the trips back and forth.

Mountain Stronghold gate lever location
Follow the soldiers up to the stronghold gate. After a short cutscene, Wash tells you the group needs to get through and continue north, and the objective becomes “Find a way through the stronghold.” Ice holds the portcullis shut, and you can’t open it from this side. The mechanism that raises it is in a small room behind the wall.


Escort the soldiers to Northwall Campground
Drop off the broken ledge, meet Wash, and go through the open gate. The objective is now “Accompany Wash to find a place to rest.” The group follows a shallow frozen stream under a stone bridge. A large, fur-covered brute drops off the rocks into the streambed and attacks with swipes, slams, charges and grabs. Hit its legs to knock it down, then climb up to its head while your pawns use ice and lightning.
Once it’s dead, climb the snowy steps past the bridge to a cave in the cliff. The soldiers set up camp there, and it becomes Northwall Campground. Activate the Portcrystal next to the camp so you can fast-travel to Norgan Portcrystal: Northwall Campground later. Take the Climbing Hook from the camp supplies. You can also rest and store spare items before you continue.

Wash and the soldiers stop at Northwall Campground. When the objective becomes “Seek the sealed study.”, only you and your pawns continue.
Sealed Study location in North Valgrian Frostgrove
The Sealed Study is underground, north of North Valgrian Frostgrove and beyond Brinerot Grotto. Its entrance is a ruined stone building with a damaged, purple-glowing Riftstone just outside. You can get there two ways. One is a short crossing that uses the Climbing Hook. The other is a longer road on foot through several large fights.

Shortcut with the Climbing Hook

Overland route through the frostgrove
Walking the whole way means more enemies, and they come roughly in this order:
- Bugaboos drop from the rocks uphill of the camp.
- A one-eyed, tusked giant breathes freezing air. Hold “Draw blade (Hold)” on the blade in its hindquarters to stagger it, and climb up to hit its eye.
- A Snowfoot starts a “Massive Enemy Encounter.” It is weak to lightning and resists fire. Go for its legs first.
- A chimera appears as “Encountered: ???” and has a magick-casting goat head and a serpent tail. Stab the goat head, and back out of its poison fog to heal.
After the Snowfoot, the path ends at a stone fort with a closed wooden portcullis that you can’t open. Go around it by climbing the rocky slope beside the fort. Pass the carcass of a large creature and go down through the broken wooden palisades into the thin woods. At the edge of the cliff, a small stone platform has two short standing stones and some Norgan Ducats. Just past it is the entrance to Brinerot Grotto.

The first Brinerot Grotto passage is a dead end. Venin Harpies attack inside, and the stairs at the end lead to an iron portcullis that is locked from the other side. Go back out and stay on the outdoor path.
Farther along the outdoor path, you’ll encounter the chimera. Once the fight is over, search the ornate chest in the nearby ruined corridor for spoils. Continue downhill and north to reach the damaged Riftstone beside the ruined doorway.
Entering the Sealed Study
Whichever route you take, you’ll reach the same building. Before entering, activate the Norgan Portcrystal: Sealed Study atop the cliff, since you’ll return here. Pass through the doorway and fight off the two armored warriors that ambush you, then descend the stairs. The “Brinerot Grotto” banner appears once more, and you can find another Climbing Hook on the supply sacks in the passage. This leads into a circular chamber containing three tall carved stone tablets. A cutscene plays; Polyeidus arrives, and the message “You located the sealed study.” appears.

Grimoires in the Sealed Study
Grimoires are scattered across the chamber’s desks, floor and shelves. Each one is a book that anyone can read to cast its spell once. Collect them before you go back up.
| Grimoire | Spell | Effect |
|---|---|---|
| High Frigor | Ice | |
| High Salamander | Fire | |
| Solemnity | Silence | |
| Anodyne | Healing | |
| Ice Boon | Ice on weapons | |
| Halidom | Cures certain debilitations |
You can also pick up Thunderous Concord, Fulgurous Lord and Igneous Melody in the same room.
How to finish Sealed History after Polyeidus’s research
Polyeidus asks for at least one day with the records, and the objective becomes “Wait for Polyeidus to conduct his research.” Fast travel doesn’t work inside the study. If you try, you get “Eternal Ferrystone cannot be used here.”

You’ll see three things that confirm the quest is finished. “The rubble was cleared from the stronghold.” appears, followed by “Completed: Sealed History.” Then The Castle in the Ice starts right away with the objective “Find a path leading east through the stronghold.” Don’t wait for a reward, because the quest doesn’t give one.
Forsaken Dominion quests around Sealed History
Sealed History is part of a quest chain that begins with Chilling Tidings. You start that quest by talking to Captain Brant at the Stardrop Inn in Vernworth between 17:00 and 05:59 and choosing “About the new Arisen…” The Castle in the Ice comes after Sealed History and has 19 stages. Finishing it unlocks three side quests in Norgan.

| Quest | Type | Rewards | Leads to |
|---|---|---|---|
| Chilling Tidings | Forsaken Dominion main | 10,000 G, 5,000 XP (Norgan Portcrystal x1 in one outcome) | Sealed History, Seeking the Sage and others |
| The Castle in the Ice | Forsaken Dominion main | — | Three side quests below |
| Quilt Me Down with a Feather | Forsaken Dominion side | 20,000 G, 50,000 XP, Firebird Cloak x1 | Back to the Temple |
| No Spoils Get Left Behind | Forsaken Dominion side | 50,000 G, 80,000 XP | — |
| Hal’s Treasure Hunt | Forsaken Dominion side | 20,000 G, 35,000 XP | — |
Chilling Tidings can be lost. It disappears once the world is covered in red clouds, and it is only available until the main quest Legacy is complete. Amos and Polyeidus appear again in The Castle in the Ice, Soul Searching and Where There’s a Will, There’s a Way. Keep the Northwall Campground and Sealed Study Portcrystals active, since the next quest sends you east through the stronghold toward Lorade Castle.
