[Critical Role] [Minor Spoilers?] Thinking about the future of the characters from Campaigns 1 and 2...

campaign 1 had a decent number of long-lived races among the main class... Half Elves, Gnomes, even Halflings. Those characters could live for many years, beyond standard human lifetimes.

by contrast, campaign 2 has much shorter- lived species in the crew... humans and tieflings, a half orc, a firbolg. most of those only have typical mortal lifespans.

if campaign 3 jumps beyond 30 years into the future, most of these characters will be either elderly or dead, meaning almost no chance of meeting them again.
