The Sunless Throne

Raise a guild, not just a single hero

The dead walk once more, and an ancient bell tolls beneath the earth. Take command of a fallen expedition guild, gather unproven adventurers, and hunt the calamity awakening below five sealed gates.

There is no single chosen hero in this story. Every expedition—and every adventurer who makes it home—builds the strength your guild needs to descend farther.

Plan short, perilous expeditions

The expedition board offers dungeons with different risks and rewards. Choose who to send, then explore a procedurally generated top-down grid where limited SP, rising encounter danger, and the road home all matter.

Reaching the exit is not enough. Defeat the elite party guarding the final path to complete the expedition. Press deeper for greater rewards, or withdraw while your party still has the strength to return.

Command classic row-based turn-based battles

Read formation, turn order, remaining SP, and enemy roles before you act. Guardians hold the front, damage dealers exploit openings, healers support the back line, and controlling enemies disrupt your plans.

More than 70 monsters and region-specific encounters await across six regions and eighteen expedition sites. Common foes wear down your resources; elites and gate bosses test the limits of the party you have built.

Build multiple parties—and keep them moving

Heroes need time to recover after an expedition. One powerful team cannot solve every problem. Raise second and third parties to take over while veterans rest, then reshape your lineup for the traits of the next dungeon.

A roster of adventurers with distinct classes and combat roles

Hundreds of skills and equipment options for character builds

Dungeon traits that alter both risk and reward

In-run ability and equipment drafts alongside permanent guild progression

A standard mode focused on roster management without permanent loss

A hard mode where fallen adventurers are gone for good

Uncover the truth beneath five gates

Descend from flooded crypts through echoing mines, a fogbound labyrinth, ember warrens, and a frozen abyss toward the Sunless Throne. Each broken gate reveals records of a dead kingdom through full-screen story scenes.

But not every victory saves the world. As the seals around the throne collapse, the power below awakens. Prepare every party in your guild to finish what you have begun.
