The region containing a legendary brass dragon’s lair is warped by the dragon’s magic, which creates one or more of the following effects:
- Tracks appear in the sand within 6 miles of the dragon’s lair. The tracks lead to safe shelters and hidden water sources, while also leading away from areas that the dragon prefers to remain undisturbed.
- Images of Large or smaller monsters haunt the desert sands within 1 mile of the dragon’s lair. These illusions move and appear real, although they can do no harm. A creature that examines an image from a distance can tell it’s an illusion with a successful DC 20 Intelligence (Investigation) check. Any physical interaction with an image reveals it to be an illusion, because objects pass through it.
- Whenever a creature with an Intelligence of 3 or higher comes within 30 feet of a water source within 1 mile of the dragon’s lair, the dragon becomes aware of the creature’s presence and location.
If the dragon dies, the tracks fade in 1d10 days, but the other effects fade immediately.
