Fenroar Dragon

"Charlie?"
"Yeah?"
"We're sinking."
"What do you mean we're sinking?"
"I mean that our boat is accumulating more water than empty space."
"OH MY GOD WE'RE SINKING!"
"...That is what I said, yeah."

— Charlie and his much more observant friend

Boggarted

Native to the dense, shadowy realms of swamps and marshlands, and characterized by their dark, mossy green scales which mimic the lush vegetation of their habitat, they possess an almost chameleon-like ability to blend seamlessly into the dense underbrush and murky waters of the fen. These dragons have elongated, sinuous bodies, well-suited to navigating both the water and land of their swampy domains.
Their eyes, glowing with an eerie luminescence, pierce through the dim light of the swamp, reflecting their keen predatory instincts. Unlike their fiery cousins, fenroar dragons exhale a noxious, fog-like gas, a breath weapon that is as toxic as the environment from which they hail. This gas not only serves as a tool for hunting but also as a defense mechanism against intruders into their shadowed realm.

Marish

Fenroar dragons are solitary by nature, fiercely territorial, and known for their deep, resonating roars that reverberate through the swamp, warning all creatures of their dominion. Their diet is as varied as the swamp itself, including both large aquatic creatures and the tough flora that thrives in the marshy waters.
Their territories are marked by their roars and the shredded remains of trees where they have decided an appropriate border around their chosen nesting spot should belong. While their territories can be tightly knit and interpersonal disputes can occur with great frequency, neighbouring fenroar dragons never invade the nesting spots of their kin, choosing only to fight over the extent of their borders.
