The region surrounding a legendary amethyst dragon’s lair is altered by the dragon’s magic, creating one or more of the following effects:
Background Check. Once per day, the dragon can cast the legend lore spell, requiring no spell components, naming any person, place, or object within 1 mile of the lair as the spell’s subject.
Crystal Profusion. Amethyst crystals and geodes form along muddy shores and lake beds within 6 miles of the lair.
Thriving Wildlife. Fish and other aquatic Beasts reproduce rapidly and thrive in bodies of water within 6 miles of the lair. Foraging in these waters yields twice the usual amount of food.
Watery Sight. Water within 6 miles of the lair is a conduit for the dragon’s psionic presence. As an action, the dragon can cast the clairvoyance spell, requiring no spell components and targeting any body of water in that region.
If the dragon dies, the populations of aquatic life near the lair return to normal levels over the course of 1d10 days. The existing abundance of amethysts remains, but new crystals and geodes form at a normal rate.
