The old bard gave no thought to the two hundred. Please don't bore me with 'In the last year, this prince bumped off the Queen and set off these reforms. Pacys sat on an outcropping of rock overlooking the sea elf city of Faenasuor. Keep the fundamentals of these locations the same, and make this a toolbox to run games in. What the exact year is clearly doesn't matter to the 5E designers, and it doesn't matter to me.

The timeline of FR is a complete mess in 5E, and I don't care enough to see it fixed. Then, pitch me a few ideas for what adventures are great there.

So for example, Cormyr is a place I'd like to know some lore about their society and why chivalrous nobility is important. What I do want is pitches on what makes each region/country unique, and what type of adventures are well-suited there. It's never mattered before Durnan and Mirt still being alive and looking the same is handwaved away with 'longevity potions.' So I really don't care what has happened in the 20 year gap (or whatever length of time it is) since these regions have been covered.
