Two Twin Keys have to be obtained for unlocking the castle in the Beorcan Castle region of Dragon’s Dogma: Dark Arisen. Both these keys are located beneath the surface in this region; therefore, one would have to explore the region and break some barriers to obtain the keys. In this guide, we will show you where to find both Twin Keys and how to use them to open the castle and collect the loot inside.
Where To Find The Twinned Keys

The Beorcan Stronghold can be reached for the first time while completing the main quest called Seek the Sage in Dragon’s Dogma 2: Dark Arisen. In the course of the quest, Dorin will give you the Grappling Hook that will help you cross the river on your way to the ruins of the stronghold, but you will encounter a strong snowstorm when you get there.
For you to be able to access the castle in Beorcan Castle, you must locate two Twin Keys in the underground areas. You cannot use the minimap to assist you in this case, but you can still access the normal map to help you locate the keys.
First Twin Key

The first key is quite straightforward to find. Step one is to get a map and locate the structure that has a brown dot on the floor. That dot represents a destructible floor, which you need to break using your bow. After breaking it, jump into the basement and collect the first Twin Key from the chest.
Second Twin Key

As for the second key, come back to the stairs that are next to the entrance of the castle and circle the building that is located close to it. Find another path downwards and go to the underground part. Once you touch the basement ground, walk through the gap in the wall and make your way to the end of the passage, where you will find another gap in the wall.
Walk around and use the ladder to climb up, where you will get the second key inside a chest near the gate. After you’ve got it, destroy the wooden obstacle and leave the area. Then you can go to the castle and open its entrance. It is worth taking your time exploring the inside of the castle, as there are a lot of loot crates and large chests filled with various rewards.
