My campaign world covers about 2000 years. Most campaigns start towards the latter end of previous game’s longer lived characters’ lives but the exact setting usually isn’t made clear to the players up front. Sometimes it’s a prequel. No characters are immortal except one vampire, some zombies, and some gods but there’s some non linear temporal locations which occasionally feature. Most campaigns start with new characters who have little to no knowledge of the previous games characters and go through the process of meeting them and filling in what’s happened in the past few hundred years. Characters come and go, but CURSED ITEMS are eternal which is fun. Most important is that everything is canon. Sometimes a campaign fizzles out. Still canon. The end of that adventure is free for the next DM to write out as they wish. Often these campaigns are considered to have had the party fail their quest.
