Eonar also blessed Alexstrasza’s younger sister, the lithe green dragon Ysera, with a portion of nature’s influence. Ysera fell into an eternal trance, bound to the waking Dream of Creation. Known as The Dreamer, she would watch over the growing wilds of the world from her verdant realm, the Emerald Dream. As a result, Green Dragons live in both the waking world and The Emerald Dream, the eldest ones flying about with their eyes closed, mind traveling the Dream.

Ysera gave all the Night Elves a kinship with nature when she gave her gift to Nordrassil, the World Tree, and allowed them to walk the Emerald Dream in their druidic studies. The Night Elf and the Tauren Druids travel through the Emerald Dream while hibernating, leading to a close relationship between these races.

More recently, the Emerald Dream has fallen into turmoil, and a foul taint has spread inside. This taint twists all life it touches, including those of the Green Flight. Many of Ysera’s most trusted kin have felt the touch of corruption, and now fight all who venture close. Below is a listing of the twisted dragons:

Once one of Ysera’s most trusted lieutenants, Ysondre has now gone rogue, sowing terror and chaos across the land of Azeroth. Her formerly beneficent healing powers have given way to dark magics, enabling her to cast smouldering lightning waves and summon the aid of fiendish, corrupted druids. Ysondre and her kin also possess the ability to induce sleep, sending her unfortunate mortal foes to the realm of their most terrifying nightmares.
Lethon’s exposure to the aberration within the Emerald Dream not only darkened the hue of the mighty dragon’s scales, but also empowered him with the ability to extract malevolent shades from his enemies. Once joined with their master, the shades imbue the dragon with healing energies. It should come as no surprise, then, that Lethon is considered to be among the most formidable of Ysera’s wayward lieutenants.
A mysterious dark power within the Emerald Dream has transformed the once-majestic Emeriss into a rotting, diseased monstrosity. Reports from the few who have survived encounters with the dragon have told horrifying tales of putrid mushrooms erupting from the corpses of their dead companions. Emeriss is truly the most gruesome and appalling of Ysera’s estranged green dragons.
Taerar was perhaps the most affected of Ysera’s rogue lieutenants. His interaction with the dark force within the Emerald Dream shattered Taerar’s sanity as well as his corporeal form. The dragon now exists as a spectre with the ability to split into multiple entities, each of which possesses destructive magical powers. Taerar is a cunning and relentless foe who is intent on turning the madness of his existence into reality for the inhabitants of Azeroth.
