Hard refresh the page, it happened to me too.
I'm willing to go as far as having everyone know Riddick from just seeing him perform. Also forgive the sparse details, truth be told, what happens in roleplay is WAY more important, especially on an adventure path. I just concentrated on adventure motivation and let the gods sort the rest.
I think everyone going to Riddick's inn could be a good setup, but again, I don't know how AOM actually starts so this could be impossible. As for personally knowing Riddick, yeah that's fine, but he won't want to talk about his little secret.
WHICH REMINDS ME
I should probably get a rank in Disguise...xD
