The verified update
Yes. Natsume describes maze-like caves filled with ore and gems within Teradea’s open world.
The evidence was checked against Natsume preorder announcement and is current to 2026-07-31. The date attached to the underlying source is 2026-05-12.
What the source establishes
- Caves are part of the diverse regions
- mining materials are explicit
- expanded movement and companions support exploration.
Why it matters
Create resource tables only after each cave and drop can be verified.
That distinction helps players make a release, platform, route, story, or purchase decision using the narrow fact actually supported by the source.
The remaining boundary
The source does not name cave entrances, floors, ore tables, or respawn rules.
Any later change should be dated and linked to a new first-party notice rather than silently overwriting the historical source.
