The Senate is a council of ten senators elected from the legion at Camp Jupiter. It gathers in the Senate House of New Rome where the senators discuss issues that arise, such as deciding whether or not quests are to be granted or whether or not to go to war.
All known Senators are active members of the legion, with veterans and ghosts sitting in on sessions. Senators are either a Centurion, a Praetor, the Augur, the Pontifex Maximus, or a god's ambassador. It is similar to Camp Half-Blood's Senior Council.
