Folio 05 / Dungeon
Throne of Hinnon
A high-level dungeon that sits outside the demo quest progression, on purpose.
Throne of Hinnon was added for the Steam Next Fest demo that ran from October 19 to October 26, 2026, and it is the clearest statement of intent in the whole build. It sits outside the demo's normal quest progression, which means you reach it by looking for it rather than by following the main line to its end.
The executive producer is unusually direct about the difficulty. It may be extremely difficult at the level you reach during the demo, and the studio treats that as the point rather than as a tuning failure. The progression deep dive frames it the same way: a good place to find out whether your first build holds up, and a good reason to go back out and change it if it does not.
Which makes it a test of the game's central design claim. If trait points really do change how a fight plays out more than a level or two would, then an overtuned dungeon is the honest way to demonstrate it. A player who reroutes their greatsword branch and comes back should notice the difference; if they do not, the system does not do what the studio says it does.
The key is deliberately hidden, and the studio says so in as many words: they have hidden it somewhere that will not be easy to find, and they ask players to share the location on Discord because they are curious who finds it first. That is an explicit choice not to publish the answer, so this page does not pretend to know it.
Folio 05.2 / Read before you go looking
What this page will not tell you
KEY LOCATION
Not published by the studio, and not guessed here
BOSS MECHANICS
No attack list, no phase timings, no damage numbers
LOOT TABLE
Unpublished. No drop list is invented to fill the gap
RECOMMENDED LEVEL
Described only as above the demo curve, never as a number
The reason for the gaps is not laziness. The dungeon exists only in a one-week demo build, the studio has kept the key location secret on purpose, and Early Access will rebalance it anyway. A guide that printed a key coordinate today would be wrong the moment the next build ships, and a fabricated loot table would be wrong forever.
