The following rules cover the basic features that can be found in structures.


Doors in structures are much more than mere entrances and exits. They can even be encounters all by themselves. Doors come in several types. Consult Table 11–10: Doors for information on common types of doors.

Most fabricated structures have some form of lighting built into the ceilings or walls. This lighting provides enough illumination for the inhabitants to see and is often controlled via a simple switch, touch pad, or vocal device. Lighting can usually be turned on and off on a room-to-room basis, though sometimes a structure’s lighting can be deactivated via a central breaker switch (usually located in some kind of control room or service area). A typical manufactured lighting fixture has a break DC of 18, a hardness of 3, and 10 Hit Points (see Breaking Objects).

Natural caverns and structures built by and for creatures with darkvision often lack manufactured lighting. Characters without darkvision must provide their own source of lighting to be able to navigate these locations.

Structure walls vary drastically in makeup, ranging from natural, unworked solid stone to reinforced starship bulkheads (though stranger walls exist). While they are typically incredibly difficult to break down or through, they’re generally easy to climb. Table 11–9: Walls contains information on the most common types of walls found in structures.
