S'darha was a game known to the Romulan race.
It was an extremely intellectual game that involved the recitation of stanzas from great Romulan literature in order to support a given argument or statement. This meant that it was a combination of debating, rhetoric, declamation and trivia games. Subcommander Avolus of the Romulan Star Empire knew of this game and had special knowledge of it.
