I have read you long posts. And I still no clear if you want official lore or a novel about sorcerers in the Forgetton Realms. And in your version of FR can a npc or man on the street tell a wizard from a sorcerer? A fighter from a rogue if the both wearing leather armour. You wall of text gave me the impression you wanted that way.
Long posts are not walls of text.
A Wall of text has no breaks or structure. It is a continuous unbroken block of words. There may be punctuation, but paragraphs to separate thoughts or segments of an argument or idea are absent. Even my longest posts are not "Walls of Text" because I have an "Enter" key and use it fairly liberally. I use Paragraphs a lot.
No. That isn't what I want. Nor is it reflected in any of my statements that a commoner walking the streets of a given town or village should be able to go "Is that a Wizard?" and be corrected by his neighbor "Nay, y'see the leather strip 'e wears 'pon left wrist? Such is the mark of a Sorcerer of the Bloodline of Leck! We're lucky t'be graced by 'is noble presence."
What I feel is that every character class in a given setting should be represented as a living and breathing element in a setting's narrative. Fighters, Wizards, Rogues, and Clerics need very little work to tie them into the world's lore. Any general or captain of the guard is either a fighter or more importantly evokes the narrative role of a fighter. Any Wizard's tower or school of magic, any church or temple, any Thieves Guild or Pirate Ship, you get the idea. These things provide a cultural context for character classes in the world, even if a given player chooses not to hold to them for their character of a given class.
It also works just great in the negative! The Evil General and his Armies of Darkness. The Necromancer or corrupt Advisor. The Cultists of the Evil God. The Assassin who comes for the King. These things -also- provide context of what the classes are
Some classes require more specific writing than the "Generic Classes", like Sorcerers or Rangers, Artificers and Druids. Because when you're writing a setting, these classes do not have a presumed role or set of roles to fulfill. The specificity of their abilities, their roles, or their identities require additional work to blend them into the world. Work that is often not done.
Most settings don't write up a whole lot about Druidic Circles or Orders because they just kind of... exist. Out in the wilderness. Little villages or wandering nomadic bands of Druids doing "Nature Stuff". They're generally just kind of written off as outsiders and hermits with the occasional mention of a "Hedge Witch" or "Lizardfolk Leaders are often Druids". Hell, even Elves in most settings don't actually fit with Druids terribly well. They're the "Nature" Race who spend decades shaping living trees into homes by carefully bending branches to grow into walls and doorframes, but they're largely led by Wizards or Clerics.
What I
want isn't something I've described, here. I've described things that I think and feel about this topic. And have asked others to share their thoughts about the same. Because what I want is really difficult for me to put into words. And as you can see, I use a -lot- of words!
