◆ Grundval · Chapter one — Hollowfort

Your cards are your character

There is no class selection screen. You become what you play. Earn class XP through your cards, unlock new abilities, build your deck, and watch your dominant class shape who you are.

Grundval is a dark fantasy deckbuilder about what is worth building. The playable chapter is Hollowfort Prison: five classes, three faction routes, and one gate.

The premise

The night Hollowfort fell

Hollowfort was built on a graveyard older than the Kingdom itself. Tonight, the dead rise from beneath its stones — and the foundations of the Kingdom begin to look less certain.

One night a sorcerer completes a forbidden ritual. The guards are slaughtered, every cell breaks open, and the hierarchy that held this place becomes contested ground.

You are imprisoned at the moment it happens — not the architect of the uprising, a survivor inside it. Three paths lead beyond the prison. Each asks you to decide what is worth building.

There is more than one way to change the world.

Signature rules

Three rules that make it ours

Health is your deck

There are no hit points. Damage removes cards from your deck, hand and combo; when nothing is left, you lose. The enemy deck is their health too.

One hand, map and battle

Exploration draws the same cards you fight with. Every action on the map spends a card, and whatever survives the corridor walks into the fight with you.

Loyalty rewrites the escape

Anarchists, guards, and the sorcerer each ask for one killing. The boss you choose is the ally standing at the exit gate.

ComboStack up to two cards a turn; they resolve left to right, with a preview of the exact outcome.
ShieldPersistent guard, capped at your max shield skill. Restores to full after a won location battle.
BarrierA ward that appears and expires — absorbs before shield, gone at the end of the round.
PoisonTicks at the start of each player turn and bypasses shield, barrier and damage reduction.
ManaRun-scoped wizard resource. Gain it, then spend all of it at once for damage or barrier.
Class XPPlaying a card levels its class. Five class levels grant a player level and one skill of your choice.
The five classes

Your cards are your character

Classes are not chosen at creation. You earn class XP by playing cards, unlock improved cards with class levels, and your dominant deck decides the portrait.

Factions

Three foundations, one uprising

Each route is a foundation under pressure — crown, knowledge, or anarchists. Commit to a branch; one route boss must fall before the gate opens.
