Concert of Worlds

The Concert of Worlds was a proposed interstellar polity planned to comprise several Sangheili worlds.

Postwar
In 2559 during the Created uprising, the Concert of Worlds was proposed at the High Gathering by Arbiter Thel 'Vadam to numerous Sangheili officials including high kaidons of several worlds. These officials couldn't come to any agreement and largely rejected the proposal. Instead, a number of them viewed the Created as the a better alternative.
