That's a link to a initial thoughts on Velious post from December 8, 2000.
"While on the subject of zones, there are also two brand new Planes for the high level players to have fun in. In addition to the aforementioned Plane of Growth (where Tunare resides), there is also the Plane of Mischief where players can encounter the King of Thieves himself ¿ Bristlebane. You can access the Plane of Growth by touching a flower inside a tower in the Wakening Land. As for the Plane of Mischief, no one has found the portal yet, but word is that it will be a dollhouse-sized castle that randomly appears in two different zones. Both of these planes are good aligned so the evil players won't have to worry about going to a plane to kill one of their gods."
