Senior Council

The Senior Council is an assembly of the Head Counselors of Camp Half-Blood along with Chiron and Mr. D, when at camp. Depending on the circumstances, other individuals are invited to attend based on their relevance. They are known to discuss wars, prophecies, and quests. They are generally held around Mr. D's ping pong table in the Rec Room. Camp Jupiter's senate debates are similar to a senior council.
