Traditionally, the Illusion rune has been taken to apply to
entertainers, a connection I've come to think was rather strained in
many cases. Why not the Life or Harmony runes, for making people happy?
Or the Magic rune to transporting people to a different world? A case
could be made for acting being Illusion, but music and painting?
The (Tentacles draft of the) Sartar: Kingdom of Heroes book provides
short descriptions of the core runes. The description for the Illusion
rune does not mention entertainers of any kind.
Does that omission indicate a change in thinking? Or is it just the
constraint of word-count?
