Bluestone Caverns sits beyond Songkeeper’s Grove in SCROOMS, and it holds its own set of scrooms to catch and log. Until you find your way in, the area stays hidden behind a “???” tab in the Index, so you cannot browse its entries ahead of time.
Quick answer: 13 scrooms belong to Bluestone Caverns, spread across five rarity tiers from Common up to a single Fabled entry.

| Nightcap | Common |

| Crystallina | Uncommon |

Rarity order in SCROOMS
The game ranks rarity from most common to least common in this order, which is worth knowing when a quest asks for a specific tier.
- Common
- Uncommon
- Rare
- Wondrous
- Fabled
Gaion is the only Fabled scroom listed for the area, which puts it at the rarest end of the Bluestone Caverns set.
How Bluestone Caverns shows up in the Index
Check the Index for area tabs. Each world has its own tab, starting with Songkeeper’s Grove, and Bluestone Caverns reads as a “???” tab until you discover the area in play.
Entries you have not caught yet appear as locked silhouettes.
Scrolling to a higher tier shows the same treatment. A locked silhouette in Songkeeper’s Grove still lists its frequency range behind its card. The Bluestone Caverns cards work the same way once that area unlocks.
Reaching the Bluestone Caverns
Getting in runs through Halden and Shax. Halden tells you that you will need proper momentum to clear the ledges at the entrance, and points you to Shax, the character with the boots. Once Shax hands over his Songtreads, those ledges no longer stop you from entering.
Two early objectives frame the trip there. One asks you to explore the Eversong and find the Bluestone Caverns, and the follow-up asks you to find your way into the Bluestone Caverns. The area tab in your Index switching from “???” to Bluestone Caverns confirms you have discovered it.
