The Conclave is the executive branch of the government, charged with implementing the laws passed by the House of Speakers and running the various governmental ministries in the Astral Commonwealth. Ministers and Conclave members are unable to vote for legislation under the separation of powers established within the people government, but may pass bills and resolutions into the House for voting.

Ministers are officials selected by the Conclave that are each given an aspect of the government to manage. They each head up large departments on their own, and are responsible for composing and presenting many of the resolutions that are considered by the government. Each Minister is only responsible for his own department, but is expected to cooperate with the other officials so that all affairs in the Commonwealth go smoothly.
