Before you start
- A tested Mistlands landing and Wisplight.
- Repaired gear, fresh food, healing/stamina meads, Rested and a clear route back to the exterior portal.
- Inventory space and a decision to leave with valuable loot before equipment breaks. Bonemass power is a useful physical-defense choice.
Confirm the entrance and clear its approach
Mines can sit below overrun Black marble buildings or inside large stone formations reached by a stairway. Seekers around a tower and a stairway into its basement are useful clues; neutral dvergr occupants indicate a different kind of stop. Clear surface enemies on open ground before entering.
Put a map marker directly at the entrance and return once to the portal so you know the path. Keep the recovery chest outside the dungeon. Enter with a full food combination and look around before moving off the entry platform.

Open one branch while keeping your retreat available
- Listen at each opening and draw a manageable group toward already cleared space. Do not destroy several wooden barricades at once or jump into a lower room before locating its return stairs.
- Watch for Seekers, broods and ticks. Roll off an attached tick promptly. If a soldier occupies a passage or a starred enemy overwhelms your defense, back out and return with better equipment instead of trading hits in the doorway.
- After the room is clear, inspect wall faces and blue-rune panels. Interact with Old dvergr gates and Hidden doors; they are not ordinary marble to mine. Search the small rooms beyond them, then return to the junction before choosing the next branch.
- Leave when your food is fading, repairs are needed or you are carrying important loot. The exterior exit is the dependable retreat; a narrow corridor is useful positioning, not guaranteed protection from attacks.

Keep three loot goals and the locator separate
Check hidden rooms before declaring a mine finished, then label the map marker with what is cleared and what remains. Some mines contain no Black cores. Expand the coastal search when a fully searched mine does not meet your target; the guide makes no fixed mine-count promise.
| Find | Action |
|---|---|
| Black core | Collect from its stand and bank it. Five build one station; fifteen allow the Black forge, Eitr refinery and Galdr table to stand together. |
| Sealbreaker fragment | Break the transparent display and collect the fragment. Keep a running count toward nine; these are not Black cores. |
| Royal jelly | Collect floor piles and brood drops for later food. Store it separately so a missing food ingredient does not force an unplanned expedition. |
| Queen Vegvisir | Interact to reveal the Citadel on your map. The boss site can require another sea journey; finding its marker is independent of completing the key. |

Recover the body before reopening the mine
After a death, leave a second load of supplies at home rather than wearing every spare into another attempt. Eat, rest, equip spare light and take the known path. Clear or lure threats away from the tombstone if possible, leave inventory room to retrieve the equipment, and retreat outside immediately after pickup.
Do not assume an old cleared marker means a mine stays empty forever. Recheck the doorway on repeat visits. If the entrance itself is overwhelmed, improve the recovery equipment or bring a willing companion before committing another body to the same spot.

You are ready when…

Saved in this browserWhen something goes wrong
A mine had no cores.
Recheck rune panels and face-pattern gates, then search another mine. Random layouts and loot mean an empty result is possible.
A doorway has become a death trap.
Return outside while you still can. Refresh food and equipment, clear the approach, and change your method; repeatedly charging the same group spends lives without improving access.
I have the marker but not enough fragments.
Keep the Citadel marked and continue the mine loop. Finding the boss does not unlock its sealed door.
