Wesley only started running the Braunsteins ~5 years ago. I don't think he was coming all that time, but not running games.
Can't remember everyone, and as comparatively small as GC I was compared to the rest, I doubt we actually knew everyone there, or could pick them out of a lineup. I mean, hell, if I hadn't killed sir jon's chariot driver/pc/etc.. so many times, he'd probably still be some random yahoo to me. (as opposed to an enumerated yahoo )
Skip 13 like a hotel elevator. Next year can be GC 12.5 "the continuation", followed by GC 14 in '22. Gotta have a "12" for the 12-sided dice. Edit/note: stuff like this is why the 12-sider is the cursed, rarely-used die at the table. It's a shape hated by the cosmic forces, or something.
