Random Dungeon Generator (RDG)

The Random Dungeon Generator is a structured system designed primarily for solo play, allowing players to experience unpredictable dungeon environments without the need for a dungeon master. It provides a reliable framework for generating dungeons on the fly, offering a blend of randomness and structured design to ensure a balanced, immersive experience. While it can be used by DM to create spontaneous settings during gameplay, its primary function is to serve as a tool for players who wish to challenge themselves in self-guided exploration or refine their understanding of dungeon structure and encounter pacing.

When using this system, the adventuring party always begins outside the dungeon, positioned within 50 to 100 feet of its entrance. The type of entrance is determined by the first table in the generator, varying from concealed cave mouths and ancient ruin doorways to imposing gates or forgotten sinkholes leading underground. This entry point sets the initial tone of the adventure, defining the dungeon’s nature before exploration begins.

The Random Dungeon Generator ensures a dynamic and self-sustaining experience, offering a means of progressing through encounters, hazards, and rewards without requiring pre-planning or external guidance. It is designed to facilitate both quick, casual play and extended dungeon-crawling sessions, making it a valuable resource for those seeking independent play.

Burrows typically serve as compact abodes for creatures like badgers, giant rats and various insects, whether solitary or social. Situated close to the surface, they rarely boast treasure. However, they may overlay other dungeon structures, a potential result that is accommodated by the generator.

Caves are natural rocky formations that present perilous terrains requiring specialized gear for safe navigation. Though sparsely inhabited compared to other dungeons, their intricate passages often delve deep into the earth, potentially intersecting with burrows and tunnels.

Crypts, seldom encountered and modestly sized and are usually without links to other dungeons. They provide spaces for undead, demons and other dark, sinister beings. A crypt may have been built as an annex to a tunnel-dungeon, to house the dead of the residents over several generations.

Tunnels represent densely occupied areas populated by humanoids dwelling within numerous dens. Continuously expanding, they're forced to defend their areas against surface and burrowing creatures, and other intruders; this allows for fortifications, trapped areas and various forms of construction. While treasures abound, stirring numerous enemies simultaneously can overwhelm even seasoned adventurers.
