Seal Cave, Dorna Ruins, and Sealed Isle at a glance.
Dungeon set list

Dorna Ruins

Extra route connections
Keep the Walkthrough Hub and Guides Hub open while you use this page. Cross-check Items Hub, Characters Hub, and Map Hub when a name or drop location is unclear. For completion tracking use the Tools Hub.
Practical session plan
Play in short sessions aligned to regions: Fulah prep, Seal Cave, Ripool, Dorna, Sealed Isle. After each session, fuse waiting relics, re-check silence accessories, and note NPC flags still owed. This page should make the next session faster—not replace saving in town.
Why consistency matters
Facts stay aligned across the wiki: single-player only, Steam and GOG launch on 2026-08-06, Romina versus Olipos and Zahal, Fulah as hub, hard-but-fair gear combat, roughly five endings, NG+ carryover or return-before-ending, touch-to-defeat on cleared dungeon enemies. If a tip contradicts those pillars, prefer the pillars and the matching hub page.
Session checklist
Before you close the game, confirm the next NPC talk, the next region exit, and whether your silence accessory is still equipped. Cross-check the Walkthrough Hub for story order and the Guides Hub if a fight spiked. Keep Items Hub nearby when bag decisions get messy, and use Tools Hub when endings or medals are the real goal of the night.
Spoiler and difficulty notes
This page assumes you want actionable help. If you are still deciding whether to buy the game, read the Review Hub first. Combat stays hard but fair when gear and books match the next boss pattern described in Boss Fights. Cleared dungeon enemies can become touch-to-defeat later, which rewards thorough first clears without forcing endless grind loops.
Continuity with wiki facts
Remember the stable facts: Konjikineko developed the game, Kagura Games published the 2026-08-06 Steam and GOG release, multiplayer is none, Romina is the librarian protagonist, Fulah is the hometown hub, and roughly five endings exist after Zahal and Olipos. When in doubt, prefer those facts plus Story Overview over conflicting memory.

Quick reminder before you go
Save in Fulah, keep healing stock honest, and do not ferry to the Sealed Isle until Cattleya and Mottl have given you the island beat. If a boss still feels impossible, change accessories and fused books before grinding. For launch timeline context, skim the Updates Hub. For cast reminders, use the Characters Hub. For spatial exits, use the Map Hub.
Closing note for map/dungeons.json
Dungeon map habits that stick
Mark teleporters, medal nooks, and boss doors in your head before you leave. Seal Cave teaches hallway pacing, Dorna teaches crystal order, and Sealed Isle teaches dual-threat focus. Use Dungeons with Crafting Builds so you never enter a named fight with empty fusion slots.
