So the text of Secrets Unveiled (card #123, side B) mentions a cultist named Victoria. I'm wondering if this might be Victoria Glasser, the artist from the CoC card game who's mixed up with the King in Yellow cult.
I played CoC briefly, quitting around the end of the collectible era due to budget constraints, and found the hints at a storyline really compelling. Unfortunately it looks like the LCG dropped this aspect almost entirely.
I'm keeping my fingers crossed.
