Did you know there are only 20 ancient dragons living in Faerun, and that three of them reside on the Sword Coast map? There’s Claugiyliamatar in Kryptgarden Forest, along with Voaraghamanthar and Waervaerendor in the Mere of Deadmen.

These ancient dragons don’t appear in Lost Mine of Phandelver or Dragon of Icespire Peak because they’re beginner adventures. Even young dragons such as Venomfang (CR 8) and Cryovain (CR 6) are potentially lethal encounters for a low-level adventuring party.

That is, if there is a combat encounter with a dragon. I personally think dragons are more interesting as a force of nature than as a combat encounter, and Claugiyliamatar presents a great opportunity to do just that in Kryptgarden Forest.

The very presence of an adult or ancient dragon affects the domain it resides in. It gives a DM the opportunity to build in clues for characters to puzzle out with Intelligence (Nature) and Intelligence (Arcana) checks.

Okay, there’s a perpetual fog throughout the forest. Shrug. Maybe it should be called The Foggy Forest.

Then a little further in, there’s an acrid whiff of something. A skunk? Someone light up the Devil’s lettuce? What’s that smell?

Then the trees get more twisted and the land gets more labrythine, and the canopy overhead is so dense with lush, green foliage that everything below is cast in an emerald green light.

That’s when the characters proficient in Nature start to feel like something isn’t right, and those proficient in Arcana start thinking back to their studies, trying to recall what all of this means. Time to roll some skill checks!

The 2024 Monster Manual has tiny beasts magically gaining the ability to understand Draconic as a regional effects of an adult or green dragon, allowing them to communicate telepathically with the dragon while within 1 mile of its lair. This is a cool wrinkle, but I feel like it’s more for the DM than for players. I’d tweak this ability by giving tiny beasts the ability to speak rudimentary Draconic.

Imagine the party tramping through Kryptgarden Forest, when a character proficient in Draconic suddenly realizes the squirrels are doing more than chittering. They’re speaking a primitive form of dragon speech!

All of these things help a DM to build the exploration pillar of adventuring into a game. To give players some insight into what they’re up against. It’s why I love regional effects for dragons and vampires and any other legendary monster that has them. They help to slowly build tension in the story.

When they do eventually encounter Claugiyliamatar, it doesn’t have to be a combat encounter. Green Dragons are social creatures and schemers.

“Sigh…If I had known there would be some halfling and elven dainties to snack on, I wouldn’t have gorged myself on hobgoblins earlier today,” says Claugiyliamatar, punctuating her sentence with an enormous belch that appears in of green, noxious cloud that escapes the dragon’s nostrils.

“I’m not hungry, but I do have an errand I require of you; as a toll for fouling my pristine forest with your stupid feet…”

And that’s when you as the DM get to decide where you want to send the party. It could be dwarven ruins, the remnants of the ancient elven kingdom of Illfarn, Kryptgarden Forest’s entrance to the Underdark (“The Orifice”), or whatever you come up with on your own for Claugiyliamatar’s dangerous and compulsory errand.
