# [Ancient Green Dragon](3-Mechanics\CLI\bestiary\dragon/ancient-green-dragon-xmm.md) *Source: Monster Manual (2024) p. 154* Ancient green dragons are creatures of legend, rarely seen by their servants or foes. Via magic and well-hidden agents, these dragons stoke suspicion between allies and undermine noble works. As bonds fray, the dragons reap rewards of greater wealth and control. Eventually the ambitions of ancient green dragons stretch beyond their territories as they seek control over empires, planar realms, or death itself. ## Green Dragons *Dragons of Deceit and Derision* - **Habitat.** Forest - **Treasure.** Arcana From forbidden forest depths, green dragons whisper evils into the world and manipulate the lives of those who listen. Elusive, conniving, and egotistical, these chromatic dragons patiently prey on the fears of shorter-lived beings, corrupting and isolating them. Green dragons might lurk amid labyrinthine wildernesses for centuries without revealing themselves; even their most devoted followers might know them only as the voice of the woodlands or a whisper in their dreams. Despite their might, most green dragons disdain physical violence, viewing combat as servants' work and preferring to trick foes into dangerous or exploitative scenarios. These dragons collect "baubles" that embody their webs of manipulation and serve as tools of extortion, such as compromising documents, family heirlooms, and sentimental treasures. ### Green Dragon Lairs Green dragons lair in ancient forests, often shaping stands of massive trees into compounds of interwoven branches, hollow trunks, and caverns amid mighty roots. They might also dwell amid forested ruins, particularly the former homes of those they've conquered. ```statblock "name": "Ancient Green Dragon (XMM)" "size": "Gargantuan" "type": "dragon" "subtype": "chromatic" "alignment": "Lawful Evil" "ac": !!int "21" "hp": !!int "402" "hit_dice": "23d20 + 161" "stats": - !!int "27" - !!int "12" - !!int "25" - !!int "20" - !!int "17" - !!int "22" "speed": "40 ft., fly 80 ft., swim 40 ft."
