Imperial Shrine

From MTG Salvation Wiki

The Imperial Shrine was the place where the highest ranking officers in the Madaran Empire had their audiences with emperor Nicol Bolas. The elder dragon needed tremendous amounts of mana to stay on a plane for long, so he usually only manifested partially in the shrine, which was located in the middle of three strong mana lines: blue from the Suido River, black from Madara’s various swamps and red from the Gitte-Yatay Mountains.

After being promoted to imperial regent Ramses Overdark stayed in the Shrine, and it was there that he fought, and lost, his final battle against Tetsuo Umezawa. The Shrine was destroyed shortly after that by Tetsuo’s Meteor Hammer spell.
