686 Ebullient Prism is an Artificial Intelligence construct, and the Monitor of Line Installation 1-4. Prism's functions include collecting and inspecting any specimens captured for evidence of immunity to infestation by the Flood.

Trivia

 * 868 Ebullient Prism was first mentioned in Halo: Blood Line, an upcoming Marvel comic by writer Fred Van Lente.
 * It is possible that Prism is an entirely different class of Monitors, as seen on the cover of Issue 2, with artificially-made tentacles stealing one of the SPARTAN-II's of Team Black.
