Pretty long article. It mentions that illithids were part of Baldur's Gate 2. Which I would probably remember if it hadn't been [redacted] years since I played it
It sounds like pc and stadia only, so not likely I'll play. My PC is long out of date and I recently quit my job with no real prospects on tbe horizon.
