You could always pull out the old thesaurus and come up with variations on storyteller.

Actually did this the other night but came up with little. Might not have used the right thesaurus, though, as "Minstral" didn't come up and I like it.

This works well especially when combined with a random adjective, preferably with some assonance about it

Hadn’t thought about this at all, but you came up with three better ideas than I've had since I started thinking about it (see, I'm really not good at this). Now to think of some good adjectives . . .
