Purpose : Except in the case of a natural cavern, a dungeon is crafted and inhabited for a specific purpose that influences its design and features.

Doors : Dungeon doorways might be set within plain arches and lintels. They might be festooned with carvings of gargoyles or leering faces or engraved with sigils that reveal clues as to what lies beyond.

Walls : The atmosphere and physical characteristics of dungeons vary as widely as their origins. An old crypt might have stone walls and loose wooden doors, an odor of decay, and no light other than what adventurers bring with them. A volcanic lair might have smooth stone walls hollowed out by past eruptions, doors of magically reinforced brass, a smell of sulfur, and light provided by jets of flame in every hall and room.

Traits

Air Quality: Subterranean tunnels and aboveground ruins are often enclosed spaces with little airflow. Though it's rare for a dungeon to be sealed so tightly that adventurers have trouble breathing, the atmosphere is often stifling and oppressive.

Odor: Odors linger in a dungeon and can be magnified by the stillness of the atmosphere.

Features: Walls are sometimes adorned with murals, frescoes, bas-reliefs, and lighting fixtures such as sconces or torch brackets. A few even have secret doors built into them.

Special: Some dungeons have walls of masonry. Others have walls of solid rock, hewn with tools to give them a rough, chiseled look, or worn smooth by the passage of water or lava. An aboveground dungeon might be made of wood or composite materials.

Lightsources: Darkness is the default condition inside an underground complex or in the interior of aboveground ruins, but an inhabited dungeon might have light sources.
