Cauldron
From MTG Salvation Wiki
The Cauldron is the former seat of power for the Izzet League in Utvara. For many years it was under the guidance of Zomaj Hauc until he attempted to incubate three dragon eggs in an effort to overthrow Niv-Mizzet and wreak havoc over all of Ravnica. It was destroyed in the following conflict, and Niv-Mizzet ordered it to be removed.
