The Ramatis system was a star system within Federation space in the 23rd century, and was the location of several Federation colonies. Ramatis III was inhabited by an indigenous humanoid population. The Ramatis system and its colonies were threatened in 2268 by the USS Sphinx, when all aboard were killed and the starship headed uncontrolled at high warp toward the system. Disaster was averted by the crew of the USS Enterprise. (TOS - Section 31 novel: Cloak) See also: Ramatis Choral Debates.
