Meditation Plane
From MTG Salvation Wiki
The Meditation Plane (also known as Bolas's Meditation Realm) was a mysterious realm that could only be reached from Dominaria, and only by skilled wizards. It was a pocket plane used as a meeting place for Emperor Nicol Bolas and his high-ranking officers. It was also used by those officers as a place for solitary meditation. The plane was constantly changing shape, sometimes reflecting the thoughts of the people there, on other occasions showing parts of their future.
Tetsuo Umezawa, the Madaran emperor's champion, often confronted Ramses Overdark, the emperor's assassin, here.
It is represented on the plane card Pools of Becoming.
