A brief note before continuing:
When I wrote the scene where they are describing who is affected by this chemical, I needed an insect species to be badly affected. I picked the Vratix without bothering to read the entire entry. The Vratix in Luke Skywalker's time are the sole suppliers of Bacta. So obviously they haven't been discovered yet. Also they are not the xenophobic whack-jobs I was going on to portray. More importantly, considering what is going to happen in about three chapters, I could not use them.
So I createdanother race none of you would have heard of. The Sulishti.
So, yes, I make mistakes.
