Ember is the only one I can remember ever reading or hearing about.
I wish 5e had, a) better art/more good art in the phb*. IMO, the last year of 4e products were about the peak of DnD art in the last decade or so.
2) Named Iconic characters in the phb.
*all due respect to the artists, there is a lot of bad, and some of it is art direction. By which I mean Halflings. But also a few other race/class images are just...not great.
There was a discussion like this on the wotc forums a few years ago, where some folks tallied up images of different types, and the data showed that 4e was more inclusive in terms of art, by a wide margin, than any other edition. I'd like that to continue, and expand to include adventure NPC families of more diverse makeups.
Im still super confused how a non DnD product is relevant? Inclusion isn't a mechanical system issue. Paizo being on the ball in their core book has no relevance outside of camparing DnD to things which aren't DnD.
Also, pretty sure the point of pointing out that he characters are fairly new is to drive home the fact that inclusion is improving, and didn't used to be very good.
