Forgive me if there’s already a topic about this, as the search function isn’t working for me, but according to an NPC on the Zyphyr Sanctum, these sky crystals are supposed to have messages once you interact with them, but when I do, nothing happens other than my Lessons from the Sky achievement tracker going up, and the sky crystal no longer being interactive.

The wiki also says “The crystals hold the recorded message of the elder of the Zephyrites.” So is that just flavor text on the wiki and from the NPC or am I actually supposed to see some messages pop up in some form?
