Lethlas guards the dream portal at the base of the tree, while several green dragonspawn guard the area, including the lake shores. It's from here Taerar intends to spread the Emerald Nightmare's corruption into Feralas. Ysondre, fearing to become corrupted again, will not approach the area, but tasks heroes to seal the portal thus breaking the connection to the Dream.
The Dream Portal becomes active for druids, providing access to the Emerald Dreamway. If the player completed , the portal will initially be locked and must be opened from the Dreamway side before it can be used.
When the Dreamway falls to the Nightmare, Lumbering Mindgorgers begin pouring out of the portal, threatening the surrounding area. Heroes fighting the Dragons of Nightmare will come here to defeat these aberrations.
