Questions about the Might and Magic universe.

Auto-translated

1) The hero Talanar is the only one who survived the deadly attacks on the Day of Tears of Fire in 566.
If Talanar already existed at that time, how did he manage to stay so well-preserved until the Isabel War in 969? As far as I know, elves live for several centuries (300-400 years), and even if we assume that Talanar lived longer than average, he should look like an old man, but judging by the image in the game, this is far from the case. Therefore, I have another question: do elves age at all, and if so, then again, explain the situation with Talanar to me. Perhaps I miscalculated the average lifespan of elves?

They definitely age. Yes, he didn't grow a beard, but he still doesn't look young in the picture.

2) What is the lifespan of such creatures?

I don't know for sure, but I assume they are immortal.

Separately, I would like to know about mages, do they live on average like all people, or do they have ways to prolong their lives (not counting necromancy)?

I won't say. I haven't heard of long-lived mages. Except for Sar-Elam, of course.

3) Does reproduction exist for such races as angels and the Faceless? If so, then how, and why didn't they restore their numbers after the losses in the War of the Ancients? If not, then why, because the ancient races of angels and the Faceless are just as ancient as the races of humans and elves who can reproduce?

These are too mature questions for this universe ;) Most likely, such things are not even thought about.
