I've done a bit of googling around but I haven't found any anecdotes of it. My rogue is daydreaming a bit about the whole Starstone thing and what it'd look like for her if she attempted and somehow passed it. I'll likely never really get an opportunity to seriously attempt it, and of course I'm exceedingly unlikely to pass anyway, but that just got me thinking if anybody HAS.
So whether it was you or one of your fellow players, or whether you were the DM and it was a player in your group... Has anyone passed it? And how did that story play out? What did they do with their newfound power?
