Surat is the First Maje of the Kazon-Mostral sect, one of the rival leaders drawn to the peace conference on Sobras that the Trabe turn into an assassination attempt in Alliances.
Surat appears in the second-season episode Alliances. Battered by repeated Kazon attacks, Janeway reluctantly looks for local allies, and after joining forces with the exiled Trabe under Mabus she proposes a conference of all the Kazon majes to negotiate a lasting peace.
Surat attends as leader of the Mostral, sitting alongside Culluh of the Nistrim and the other sect chiefs. Like them he is suspicious and quarrelsome, more interested in old grudges than in Federation ideals.
The meeting is a trap of Mabus's making: a Trabe ship rises outside the window to gun down the assembled majes. Janeway realises in time and warns the room, and Surat escapes with the rest, leaving Voyager with every sect as an enemy and Janeway resolved to hold to Starfleet principles.
