I'm expecting absolutely none of us to be right and we would have been better served discussing the themes and arguments presented in the books than conjecture!
Check this out:
Meigon (4002- )—A member of the Dûnyain Pragma.
Uän, Samarmau (4001- )—One of the Dûnyain Pragma.
Interesting to me that
1. These guys lived over a hundred years. Product of inbreeding with Nonman blood in the gene pool or was it something else? Might be good to check how long Anasûrimbor kings naturally lived. I wanted to make a thread about this since apparently Triamis the Great lived over 120 iirc.
2. Both were born within a year of eachother. Are the Dunyain hatched in cycles or something?
3. No death date. The prologue only mentions the elder Dûnyain were on the parapet and the polluted ones would die so maybe they weren't among them. But if they were, this seems to leave open the possibility they didn't kill themselves.
