What to know
- Call of the Lost is an Anomaly Commission that unlocks a boss encounter
- You must reach a rooftop location in New Herland District to trigger it
- The boss tied to this mission is the Nestbound Bird
- Completing the commission unlocks the boss permanently for future fights
You will encounter Call of the Lost as part of the anomaly system in Neverness to Everness, and unlocking it is more about finding and triggering the right commission than progressing through a traditional boss gate. Once you understand how anomaly commissions work, this becomes a straightforward unlock with a hidden location twist.

How the Call of the Lost unlock actually works
The Call of the Lost boss is not directly accessible from the start. Instead, it is tied to a specific anomaly commission. You first need to activate and complete the Call of the Lost mission, which then unlocks the boss encounter tied to it.
This system is consistent with how NTE handles anomaly bosses, where you must engage with world-based events rather than menu-based boss entries. Once completed, the boss becomes available for repeat encounters.
Where to find the Call of the Lost location
The mission takes place in New Herland District, specifically on a rooftop south of Oia Avenue.

You are not guided directly to the boss arena at first. Instead, you need to:
- Navigate to the marked area
- Climb up to the rooftop
- Look for a torii gate structure, which acts as the boss trigger
This rooftop positioning is easy to miss, especially if you’re only searching at street level.
How to unlock Call of the Lost in Neverness to Everness
Step 1
Track the Call of the Lost anomaly commission from your mission log and head toward New Herland District.

Step 2
Locate the building south of Oia Avenue and begin climbing to the rooftop area. The game does not always highlight the vertical path clearly, so manual exploration is required.

Step 3
Once on the rooftop, search for the torii structure. This object is the key interaction point that starts the boss encounter.

Step 4
Interact with the torii gate to trigger the Nestbound Bird fight. This action officially unlocks the boss.

Step 5
Defeat the Nestbound Bird to complete the commission. After this, the boss is considered unlocked and can be accessed again through anomaly systems.

Why the boss might not unlock for you
If you’re struggling to unlock Call of the Lost, the issue usually comes down to one of these:
- You haven’t accepted the anomaly commission yet
- You are searching at ground level instead of the rooftop
- You missed the torii interaction trigger
- Your Hunter Level may be too low for the commission to appear
Because NTE uses a dynamic anomaly system, some commissions only appear after progressing your account or completing prior tasks.
NTE Call of the Lost rewards
Unlike traditional RPG bosses, Call of the Lost represents NTE’s environmental storytelling design, where bosses are embedded into the world rather than separated into instances.
| Reward Type | Amount |
|---|---|
| Hunter EXP | 300 |
| Annulith | 40 |
| Fons | 15,000 |
| Silver Carrota | 80 |
| U-00NE | 30 |
| Beetle Coins | 7,500 |
| Material Box | 5 |
| Arc Reward | Tears Beneath the Mask |
These rewards make the boss worth unlocking early, especially since Annulith and upgrade materials are valuable for progression.
You are essentially acting as an Appraiser investigating anomalies, which is central to the gameplay loop of Neverness to Everness.
This makes unlocking bosses feel more like discovering hidden encounters rather than simply progressing through a checklist.
Unlocking Call of the Lost is all about exploration and interaction rather than grinding or gating. Once you reach the rooftop and trigger the torii, the boss fight becomes available immediately.
If you approach it with the mindset of finding anomalies instead of chasing boss markers, you’ll unlock it much faster and understand how similar bosses work across the game.
