D&D Alignment - J. Tweet: https://www.enworld.org/threads/alignment-in-d-d.671817/post-7979332
As a historical aside, I think I may have invented the word "Psion." Back on the old WotC message boards, back in the run-up to 3E, back when Ryan Dancey was posting a lot...in those conversations I posted a list of core classes I'd like to see for 3E. At that time, I assumed that the 2E "class groups" (Priest, Rogue, Warrior, Wizard, Psionicist) would continue in 3E. In my chart of proposed classes, I introduced "Psion" as the name of the class group. I felt the "-icist" was not essential to the name. Soon after that, "Psion" entered the discourse.
Of course this more succinct name could have been readily intuited/invented by others, and it would be hard to prove, without looking back at the msg board archives and interviewing the designers from back then. Anyway, it's just a little detail within the D&D Multiverse. And, off hand, I don't even remember my msg board handle from that time. But a bit of speculative history.
Also co-authored, with Shawn Stanley, the name of the official Mystara website: Vaults of Pandius.
