From whence comes the term "Ionite Nebula"? (DS9 core rules, p.19). It's not in the Encyclopedia, but I remember seeing it on the captions on a DS9 episode (Way of the Warrior, I think): '[Klingon]: What is a Lurian doing so far from the Ionite Nebula?' They may not of said 'Lurian', because I think the species name was established first in "Who Mourns for Morn?", but I'm sure that it was said in reference to Morn.
