1. The sentence reads much better with "that". One could leave it out, but one would have to pause after "said".Originally Posted by Helped Wanted
2. No, no comma is needed after elixir.
3. The "who" in the last sentence is a bit odd. It tends to depoersonlize the last statement, making it almost seem that the goddess is someone else. I would place a semicolon after "moon" and change "who" to "she".
