The region surrounding a legendary sapphire dragon’s lair is altered by the dragon’s magic, creating one or more of the following effects:
Crystal Profusion. Natural stone within 6 miles of the lair grows plentiful crystal formations and veins of sapphire gemstones, particularly underground.
Stony Sight. Natural stone 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 natural stone formation in that region.
Telepathic Enhancement. The dragon’s psionic energy enhances the mental powers of other creatures. Any creature capable of telepathic communication has its telepathy range doubled while within 1 mile of the lair. This includes creatures with innate telepathy and magical telepathy such as the Rary’s telepathic bond spell.
Thriving Wildlife. Giant spiders (a sapphire dragon’s favorite prey) are attracted to the area within 6 miles of the lair and settle there in large numbers.
