You read a different series from what I’ve got on my shelves.
Born to fullfill a prophecy is another background he has (His palms get brands in the shape of a heron that are the marks of the Dragon Reborn in the prophecies )
He is half Aielman in race.
Definitely archery trained starting out at the very beginning and sword use too
I may be squashing a few things together he got his first Heron marked blade from
Tam (his dad), and he single handedly killed a monster while still in the first book. And he is channelling without training in that so yes he discovered that part (its rather hinted at he does it healing a horse)
You were right he was raised by a farmer THIS kind of farmer.
Tamlin al'Thor is the adoptive father of
Rand al'Thor. He lives on a farm in the
Westwood near
Emond's Field, where he raised Rand from a baby.
He has a thick chest and a lined face. His hair was gray with sprinkles of black at the beginning of
998 NE, but by the middle of
1000 NE, it is completely gray. He is described as being solid in virtually every conceivable way.
He has been shown to be a superbly skilled warrior, both with a sword and perhaps even more so with a bow. He essentially never misses a shot, and his capabilities with a blade were such that even
Al'Lan Mandragoran saluted his skill.
