You glean some very interesting worldbuilding insights by playing a game I like to call "what two concepts are virtually identical in real folklore, and completely unrelated in D&D?" And then just... make them related.Anyway, D&D Bards are the only D&D class with absolutely no meaningful tie to its inspiration at all, and that’s a problem.
For instance, wandering priest-judge-poets with supernatural powers of persuasion?
Of course, forty-some years of D&D history have taught us this is the Celtic Bard, thought "priest" and "judge" have fallen off along the way. It's a good archetype.
In Arabic, I would have just described the sha'ir. And what does it tell you about your world, if you take the D&D version of the Celtic Bard and the D&D version of Arabic Sha'ir and you decide they've really been the same thing all along?
D&D is better when it doesn't try to place itself in any recognizable historical time or place, thematically: it benefits from mixing and matching elements from the ancient world through the near-modern period, from battleaxes to bifocals.
Yessssssss. Since D&D has been homogenized fantasyloaf since its inception, how better to enjoy it than dipped in a hearty anachronism stew?
