That's not quite how it was.In 1e the Bard followed the path of being a Fighter/Thief at first. One of the stipulations of that time were that Thieves could NOT be Good. Afterall, the thought was that thieves main focus was...thieving. Taking things unlawfully from others was not seen as good (ironically though, I think you could be lawful neutral...which would be...interesting).
Again, bards in AD&D 1E had a bit more freedom than this when it came to their alignment; check out the last sentence in this section:Then, after you got to a certain level, you dual-classed or had a special rule for multiclass characters to become a Druid. Druids also were supposed to be neutral...aka...not good (OR evil).
That's true to a degree. They did conceive of the bard as a wandering minstrel, rather than an orderly class. In 3.5, though, Loremaster was a prestige class that not just bards could qualify for, but also sorcerers, wizards, clerics and even druids. It wasn't a bard specific thing, so "monarch's official lore master" could be lawful, but not if he was a bard or druid(though I don't know why a druid would go that route).It’s in the text about alignment for the bard. They conceived of the class in that one way and didn’t really consider anything else like a monarch’s official lore master or any other concept other than roguish, wandering entertainer.
