actually, he landed a bit behind the root.... more on his shoulders than his back.
And remember the square-cubed law....
v2=v1(l2/l1)^3 for volume
a2=a1(l2/l1)^2 for surface area
According to my calculations, assuming rahan is 2.5 feet tall, a human at his scale would weigh about 14 pounds. He's also a sturdy example of their species, having (as intimated) worked in the smelters since he was 5.
He's small, light, very muscular, and struck the ground loose-limbed from a proportionately very low height (Going by his height, maybe 6 to 10 feet.) So he's liable to escape with little more than some bad bruises, maybe a sprain or two, and a nasty headache.
Writing Rahan's dialogue was.... difficult. Having him say WHY he hated Quentyn so much meant digging into things, trying to see things through Rahan's eyes.
What was the perspective?
Rahan is an "Ironmonger's" son.
Now, an "ironmonger" is somewhere between a junkman, tinker, and blacksmith, culturally--- making his living collecting scrap metal, melting it down, and reselling it as ingots... maybe doing metalcraft and repairs as a side issue. Any aspect of this is hard, sweaty, grueling, and somewhat dangerous work.... and not one likely to garner a lot of respect in the upper crust.
Consequently Rahan's dad is most likelyhard-working and hard-nosed.... Rahan's early years were probably filled with hard work and strict upbringing. Not cruel or unfair, but.....Zero slack. Emphasis on hard work, pulling your weight, being "tough," quit whining, be a man.... and a lot of scorn for people who couldn't.
Then along comes this runt... puny, dewy-eyed, can't hold his liquor, can't pull his weight, everything Rahan was taught is contemptible and inferior. He beats him up, the little punk whines and cries.... which in Rahan's world just shows that Quentyn's a weak, whiny crybaby who deserves to get pummeled.
And now the little turd-- who is still weak, still whiny, still puny--- is being honored and feted by everyone, even though he's screwed up colossally over and over again!
And being "suddenly rich" doesn't make it much better. They may have experienced a sudden rush of prosperity due to the metal shortage, but it wasn't like the wealth fell out of the sky on them. It wouldn't have mattered in the least if Rahan's family hadn't already been working hard in the industry and used foresight, established the trade contacts, carefully maintained a large "buffer" stockpile of raw metal, and bought low with an eye towards selling high.
But, demonstrated by how Quentyn first referred to Rahan ("take a bum and make him wealthy ,") they were probably treated like most <a href="

Rich people get respect. Hard working people get respect. Strong, tough, athletic young men get respect. So how do you react when you're all those things--- and someone who is NONE of those things gets treated with more respect than you?
Mind, none of this whatsoever is an excuse. There's a chasm of difference between an explanation and a justification. Rahan's lack of introspection--- his inability to consider that maybe it's his boorishness that costs him socially, and that taking his bottled anger and pouring it out on someone who had nothing to do with the cause did nothing for him--- is reason enough to condemn him. But it does clarify WHY he has harbored such maliciousness for so long.
