Hollow Spiral

Hollow Spiral is a full DAI main experience built around endless procedural survival exploration.

You begin inside a single room suspended in a void. From there, you can generate new rooms in six directions: north, south, east, west, up, and down.

Every coordinate is rolled only once. Once a room exists, it stays there permanently, allowing the dungeon to grow into a massive interconnected survival world instead of resetting like a traditional roguelike.

There is no final floor.

There is no fixed progression path.

Survival is the progression.

Rooms can contain farms, villages, mines, groves, castles, ruins, oceans, volcanic environments, Nether regions, crypt rituals, libraries, smithery rooms, deep-dark encounters, End relics, and more.

Current room families include:

• Siege-damaged ruins
• Carrot and wheat farms
• Eight tree-grove biome variants
• Ten-grade depth mines
• Lush caves
• Animal pens
• Eight randomized crypt rituals
• Libraries and enchanting rooms
• Smithery rooms
• Five tiny village styles
• Flooded ocean environments
• Five castle variants
• Witch-occupied cavern variants
• Volcano rooms
• Nether wastes
• Nether fortresses
• Deep Dark rooms
• Rare End relics

Horizontal paths can loop back into already-generated rooms, while vertical stair systems allow the Spiral to grow upward and downward indefinitely.

Hollow Spiral uses DAI's experience system, dedicated title screen, expedition save browser, and native void-world generation.

Requires Decisions and Impulses / DAI 1.9.5+.

The HollowSpire Resource Pack is the intended visual companion.
