What Are Sealstones in Valkyrie Profile 2: Silmeria?
Sealstones are the dungeon system of Valkyrie Profile 2: Silmeria: items with special effects, found on daises and in shells inside dungeons, that change what is true in the space around them. The game's own manual documents how they work, and this page follows the manual and the documented gameplay record. Placed well, a sealstone is a weapon. Placed badly, or carried carelessly, it is a liability that follows you.
THE SYSTEM IN FOUR PARTS
Per the game's manual and documented gameplayWHY IT MATTERS
The dungeon as an argumentRead together, the four placements turn every dungeon into an argument about its own rules. The stones you find are not equipment in the usual sense; they are conditions. Moving one from a dais to a shell can switch off the effect that was protecting a corridor. Carrying one trades a party wide benefit against the loss of the area effect it was exerting. Restoring one is a small investment of magic crystals that converts a local accident of the dungeon into a tool you own for the rest of the game.
It is also the clearest single example of how Silmeria differs from its predecessor. The first game's dungeons ran against a clock of periods; Silmeria removed the clock entirely and put its pressure here instead, into space rather than time: not how long you may stay, but what the ground does to you while you are on it.
