Hello friendly friends

In Clanbook: Malkavian Revised (p.27) it talks about how the mute Pelinka came up with the clan symbols initially, but then it references another Malkavian who painted them on chairs for a grand clan convocation (presumably meaning the Convention of Thorns). I'm fairly confident this "symbols on chairs" scene appears in a book, but I'm not sure if it's Transylvania Chronicles II or another book. Can someone help me out?
