Psionics was back in AD&D I have never played or even looked at Dark Sun or 3E or 4E for that matter but we tried Psionics when playing in the early/mid 80s and using AD&D. So I am pretty sure players of that vintage would be aware of Psionics well before Dark Sun came along.I'd bet most D&D players probably aren't that familiar with the word, unless they played in Dark Sun or AD&D. It was part of 3E and 4E, but not heavily, and even in 2E it really wasn't that big outside of Dark Sun. Outside of these groups, I would doubt many people would even believe it's a word.
