Green dragons are a classic. These are the forest dragons, that hide deep in the greenery, stalking prey and hording treasure. They are more likely to interact with humans and elves, due to their location, and could even be called playful, if not for how malevolent their play is. I lean into Celtic naming schemes, and a little bit of British fairies for their personalities, as it ties in nicely with the forest theme.
Our youngest green dragons.

Tonwen The Heledd, Very Young Green Dragon, CR 4
Tonwen The Heledd is a cocksure young dragon. After claiming an orchard, the local villages sent a band of adventurers to oust the threat. Unfortunately for them, Tonwen slew them outright, and as retaliation destroyed some outlying farm houses. With their adventurers slain, the townsfolk are not really sure of what to do next, and Tonwen has started making demands.

Lair
Tonwenn lairs in an apple orchard on the outskirts of the hamlet of Oshwallt. Here, he has found success in defending “his land” and seeks to expand his influence. The orchard is a small 2 acre plot filled with neat rows of apple trees, that Tonwenn takes great pleasure in melting with his breath.

Horde
Tonwenn’s claim to fame at this point is the slain band of adventurers. He has fashioned scarecrows in the center of his orchard dressed in the armor of his victims, and keeps their gems and potions on him in a small pouch.
