What does hematic mean?
The MUSH has a Dune theme, so ‘thematic’ means that something is drawn directly from the Dune novels by Frank Herbert, or is consistent with information presented in those books. The planet Kaitain, the Great Houses, nobility and swordfights are thematic. Lightsabers, and warp drives aren’t. We take the Dune novels by Frank Herbert , from Dune up through Chapterhouse: Dune, to be canonical. There are many wonderful sources available that depict various aspects of the Dune Universe, including novels, films and encyclopedias. However, for purposes of this game, we assume only facts presented in the Dune novels written by Frank Herbert to be true.
