Description
Obsidian dragons were once included within the fold of gem dragons as it is known today, however, for reasons unknown even to the oldest of their kind, the gem dragons were cast out by their god, Sardior. According to legend, the obsidian dragon, Seradess, who was their thane and representative when dealing with the other gem dragon races was destroyed by Sardior, who promptly banished the entire species. It is unclear if they were banished for their tendencies towards villany, or if these tendencies developed in response to their banishment. In either case, obsidian dragons are among the most volatile and dangerous of their kin.
Obsidian dragons are incredibly powerful. Among gem dragons, they are only surpassed in raw might by the mighty amethyst dragons. However, their ability to plan, react, and adjust is unparalleled. Possessing intellect to rival an archwizard from birth, their mental capacity only grows with each passing age, making them the most intelligent of their kind. Coupled with a fierce temper and imperious nature, they are incredibly dangerous to be around, and certainly lethal when made into an enemy.
Ancient Obsidian Dragons
By the time an obsidian dragon is old enough to be considered ancient, its scales are pure black and have become so small that it appears to have smooth, glassy skin, with only their joints displaying the razor sharp edges for what they truly are. These creatures are among the most callous, cruel, and calculating to ever operate within the multiverse. By this time in their life, they likely have extraordinary plans in motion that might impact entire kingdoms, or even worlds. They care little for anything aside from chasing their own intellectual pursuits, which often involve consequences for countless creatures around them.
Lair and Lair Actions
Obsidian dragons make their homes in active volcanoes and mountainous regions in warmer climates. Older dragons with the ability to travel between planes may even make their lair on the Elemental Plane of Fire.
The region containing an adult or ancient obsidian dragon’s lair is altered by its presence, creating the following effects;
Obsidian Profusion. The temperature of any natural water sources within 6 miles of the lair increases to near-boiling, and sheets of obsidian can be found covering the bottom of any lakes or ponds.
Fiery Sight. Fire and lava within 6 miles of the lair become conduits for the dragon’s psionic presence. As an action, the dragon can cast the clairvoyance spell, requiring no spell components and targeting any area of fire or lava in that region.
Thriving Wildfire. Fire elementals and other creatures of elemental flame are attracted to the mountains within 6 miles of the lair, migrating and hunting there in large numbers.
If the dragon dies, the populations of elemental life near the lair return to normal levels over the course of 1d10 days. The existing abundance of obsidian remains, but new obsidian forms at a normal rate.
