Time to break hearts: Ages of LOK characters at the estimated time of the Cataclysm
Avatar: Seven Havens takes place 225 years after The Legend of Korra. We don't know the precise timing of the Cataclysm, but, considering Bryke often utilize round numbers, there's a common fan idea that the Cataclysm was 25 years after LOK, then ASH is 200 years after the Cataclysm. My post uses this estimate for the below ages. Based on Korra's appearance in the trailer, if this isn't right I don't think the truth is too far off.
Keep in mind that it's possible not everyone died during the Cataclysm. They could have survived awhile longer, but I think it's likely most or all died in or around the Cataclysm (ignoring possible earlier death dates from other things). The numbers are also assumed to be after people's birthdays. If they hadn't had their birthday at the time of the Cataclysm, just subtract one off the number. Treat these like minimum ages the characters made it to I suppose. Let me know if there are any others you want added to the list or if you have any corrections. With that out of the way, here are the estimates from youngest to oldest in 199 AG / 10028 AWHC.
EDIT: I'm really surprised by how many people think Korra was in her 50s or 60s during the Cataclysm. Here's my post about Korra's age and why she looks mid-40s (https://www.reddit.com/r/TheLastAirbender/s/k1rnggm60x). Basically, she looks almost identical in age to her father in LOK Book 4 when he was mid-to-late 40s.
