Back on this topic again: Megan and I discussed the idea of adding a catch-all for minor characters in the 7DTD series again recently, and we agreed to hold off on that until after I fleshed out the stub article for the Chaos Beasts.
However, in practice I'm working through the series in sequential order (on my 3rd pass now, I think), and I'm realizing that it would be a lot easier for me if I had that page available to start filling in as I go.
Again, for the record, I imagine Other Characters covering minor characters who either pop up for a single episode (Adam's "God," the Very Finest Pig, or the Russian pig-mongers), as a non-speaking role for a slightly longer stretch (Sign & The Jade Grue), or are repeatedly discussed but never actually appear in person (Grace, Granny Omega, & the "Warlord"). With the general notion that if any of these characters ever becomes more significant they would get moved to their own page.
So, anyway, long story short that page would be very handy. Feel free to leave it orphaned (don't modify the homepage links) until I've filled it out. (Grace and The Jade Grue will be the first additions.)
