Oh yeah! It was you who first used the Teledahn/Sharper metaphor.. I'd forgotten.
I think we'll need wholly original Ages as well as restored ones, or we'll be another Restoration Council instead of Writers. There are a lot of people who feel very strongly about sticking to entirely new content, though I personally would want to refer to the D'ni universe myself. IC, Model 4 is where the Guild of Writers writes a new Book, which both the Guild of Maintainers and the DRC approve before it's eventual display in cavern. OOC, it is where an independent development team works on an original concept with little connection to Cyan other than the eventual assurance that the final product is majorly bug free. I don't know if there's anything else to be said about it, it's a more simple case than the others really.
