They do still say “Yub Nub” in the SE, Wicket says it to Leia when trying to get her to go to the village. “Freedom” maybe be the name of the village (I know it’s “Bright Tree Village”, leftover from Legends).
That’s right too! The sound of a pan flute causes me a deeply unsettling physical sensation, far worse than an alto saxophone. I’m fully on board with Adywan’s decision.
