In the Crowcaller main quest during Chapter 5, Kliff must track down an invader hiding within Hernand Castle. The objective only gives a general search area covering the entire castle, so finding the exact path through the interior can be tricky. The invader is reached through an Abyss Gate on the second floor, which teleports you into the Axiom Archive where the confrontation takes place.

Destination |
Fast travel back to Hernand town if you are not already there. Head to Hernand Castle and approach the inner courtyard. Enter the main castle building through the front entrance.
Once inside the main hall, turn right. You will see a staircase leading upward to the second floor. Take either the left or right staircase, both lead to the same upper landing. Climb to the second floor.
The castle has many rooms and locked doors on this floor, which is what makes the search confusing. Most of the doors you can interact with lead to empty rooms or are locked. The room you need is specifically on the left side of the corridor.
On the second floor, look for the wooden door on the left side of the corridor, toward the back. This is the same room you visited during your first trip to Hernand Castle earlier in the story. If you remember that earlier visit, the room will be familiar.
Enter through the door and look along the walls for a section with a distinct yellow tint. This is the Abyss Gate. It looks like a glowing yellow wall or portal surface and stands out from the normal stone and wooden walls of the castle, though it can blend in with the castle decor if you are not looking carefully.
Walk up to the yellow-tinted wall and press the interact button. The Abyss Gate teleports you into the Abyss, which appears as a sky map floating above the ground. You will spawn at the entrance to the Axiom Archive area.
Some players have reported that the Abyss Gate interaction prompt does not appear when standing in front of the yellow wall. If this happens, there is a backup method:
Open your map.
Press R3 (Right Stick) to toggle the map view.
Look for a fast travel point in the sky above Hernand Castle.
Press Triangle (Y on Xbox) on the fast travel point to enter the Abyss area directly through the map.
This workaround always works and bypasses the physical Abyss Gate interaction entirely.
Once inside the Abyss area, move straight forward toward the tall tower building ahead of you. As you approach, enemies will spawn. These enemies are tougher than standard foes you have faced up to this point in Chapter 5, so come prepared with recovery items and ensure your gear is upgraded.
Fight through all the enemies in the tower area. When the last enemy falls, a cutscene triggers automatically. This cutscene completes the quest objective and advances the Crowcaller storyline.
Step | Action | Location |
|---|---|---|
1 | Enter Hernand Castle main building | Ground floor |
2 | Turn right, take stairs to second floor | Main hall staircase |
3 | Enter the left door on the corridor | Second floor, back left |
4 | Interact with yellow wall (Abyss Gate) | Inside the second-floor room |
5 | Go forward and defeat all enemies | Axiom Archive (Abyss sky map) |
The Abyss Gate can be easy to miss because the yellow wall blends in with the castle decor. If you cannot find it, look carefully along every wall in the room for a faint golden glow.
This is the same room and the same Abyss Gate you encountered during your first visit to Hernand Castle. If you remember that earlier scene, it helps narrow down which door to enter.
The enemies inside the Axiom Archive are noticeably stronger than normal Chapter 5 enemies. Bring extra healing and consider upgrading your weapon beforehand.
If the Abyss Gate interaction button does not appear, do not waste time searching other rooms. Use the map-based fast travel workaround immediately.
After completing this objective, the Crowcaller quest continues with additional story developments. Make sure to follow the quest marker for the next step.
