The way I see it, tables are only half the story, and the other half is for another GM to look at and go 'hmmm... okay that's what this means.' 

30, for instance. I could say 'oh this is for a ritual where you catch something outrageous by baiting a fishing line with the caterpillar and whatever you catch is bound to be your loyal steed for a year and a day and some mustache-twirler planned to catch a dragon with it to destroy his rival in love but abandoned it because he found out that his rival had been called off to war where he'd surely never return, leaving the fair Melissandra to remain an eligible bachelorette'

But since every campaign is different, I think it is better to give you a fraction of that and let you fill in the gaps with stuff that suits your campaign and your players.
