Description
Cousins to the great dragons, wyvern have two scaly legs, black leathery wings, and a sinewy tail topped with a poison stinger that can kill a creature in seconds.
Physically, black wyverns are most distinguished by their wings, which protrude from the sides of their body and have long sharp claws on the end, projecting forward. A large frill adorns the upper part of the neck. They smell like rotting vegetation and foul water, or like the powerful acid they can breathe.
Lair and Lair Actions
Sight
A massive wide cavern, high ceiling, smooth walls from the wyvern body scraping the sides, coins, jewels, precious metals, weaponry and other riches scattered on the floor and piled up in adjoining chambers, heat vents, fissures, stalactites and stalagmites…
Sounds
The crash of water and waves (if located on a cliff face on the ocean’s edge), powerful inhaling and exhaling that reverberates throughout the chamber, the scuff of a foot, the drag of a tail, knocking over a stalagmite with a crash, a metallic slide of metals and coins…
Smells
Fire, blood, metal, char, brimstone, the sea, salt, hot stone, musty air, rotten food breath, death
Tastes
Sour tang of fear, sweat, dry mouth…don’t think you want to stop here for a picnic
Touch
Rough handhold climbing up to the lair entrance, stone digging into knees, cutting hands, scraping legs and arms, inside: taking careful steps, picking your way across a floor littered with bones, rock and riches, careful not to disturb anything, pausing to wipe away droplets…
