well, i searched for the rumor but it never appear
i used the "unlock all rumor" cheat and the rumor still doesn't appear. the item chest itself appear though.
on a side note, the rumor for "legs of ehecatl" never cleared after i got the item. got no consequence on the game though. also this game is pretty good --- Giovanni : hahaha Im the caid of my shoes and i control every toe-nail in it.
