Klingonaase was the Klingon language in the continuity of the TOS novel The Final Reflection and the FASA RPG, and in later novels and works from the 1980s which drew from those sources. It was generally superceded by tlhIngan Hol developed by Marc Okrand for movies and television series after 1984, but recent novels by Keith R. A. DeCandido have worked some words and concepts from TFR into the now-canonized Klingon culture.
