"First Born" is the first book of the Elven Nations trilogy. This novel, as with the rest of the trilogy, is passably solid. The trilogy is an entertaining, even-keel story about an important time in the history of Krynn. It avoids annoying D&D cliches and even incorporates some squarely adult themes.
The characters, though, are a tad bland: Kith-Kanan, the Silvanesti prince cum Qualinesti founder is about as interesting as a paper bag, though it's probably more accurate to say a paper bag with a penis, since this dude is constantly swooning and obsessing over chicks. Upon his return to Silvanost after a formative, coming-of-age experience off the grid with the some crunchy wild elves (one of whom he bangs before she turns into a tree), he sees his ex-girlfriend, now brother's wife, and is like "oh gosh she's so, so beautiful. Do NOT bang her. DO NOT BANG HER." Well, he does. Another time when he's about to be run through by General Giarda after getting his ass pummeled by him (like fucking *pummeled*), Suzine, a human he's been randomly crushing on even though he doesn't know her at all and is literally the enemy general's wife, crashes a mirror down on Giarda's skull in a bid to distract him from murdering Kith. Kith-Kanan's immediate response, as glass shards go flying and Giarda's skull crunches with blood sluicing out, is not like "oh, fuck! What was that?!?!", but "oh my gosh I want to bang her so badly". Literally his first thought, which is just unbelievable. Which, he does, resulting in two half-human-half-elf heirs to the Qualinesti throne that he basically neglects once his human wife gets too old and decrepit to reliably bang anymore (remember, elves on Krynn live for thousands of years). Ulvian, the Prince, is destined for cosmic-level douchebaggery.
While "First Born" is generally occupied with Kith's sylvan frolic, it sets the stage for conflict between the elves of Silvanesti and the humans of Ergoth. These battles, recorded in book 2, "The Kinslayer Wars", are grand. Who doesn't dig surprise-routing a standing force of fifty thousand soldiers with hundreds of shrieking, diving griffons ridden by elves firing arrows, sending horses and men into panicked flight. With the dwarves attacking from the south, the much-outnumbered elves are able to keep the Ergothians at bay, filling 10 ft-deep trenches with human corpses.
Though there is generous gore, greater effort could have been paid towards the geopolitical aspects of this conflict, which, as they stand, are patently unsophisticated: Ergothians want land that is de jure Silvanesti, but is in reality a smattering of remote villages isolated economically and culturally from Silvanost. One element of all this is never really elaborated: why are millions of people getting killed in a war spanning 40 years to occupy a basically barren, unremarkable plain?
"Kinslayer" ends with the formation of Qualinesti (the nation of relatively free-spirited and tolerant elves, half-elves, and humans), which seems to lack a decisive moment in the text. It seems almost an afterthought, an assumption that Kith and his not-totally-but-just-a-little-racist elven comrades will basically peaceably form a new nation. There isn't a spate or bad blood per se, beyond a moral mismatch over slavery and the importance of racial purity: Kith thinks one or two slaves is grand, but jesus christ not 10 for fuck's sake. But basically the Silvanesti are high fantasy Nazis, obsessed with protecting bloodlines from perversion by wild elves and humans, insular more than genocidal, though imperialistic to a fault (remember the empty plain that simply must retain or else).
The weakest novel of the trilogy is number 3, "The Qualinesti", which finds itself occupied for what seems like too much time on trivial subplots, like Verhanna tracking elusive slavers and carousing with a herd of depraved, alcoholic centaurs; or the pursuit of the evil wizard Dru by the royal guard and Kith-Kanan himself. Dru morphs into a wyvern (a fucking wyvern, not a dragon mind you, which is a nice treat): and what's the difference between a wyvern and a dragon you ask? A wyvern has no arms, just two legs and two wings. Does wyvern Dru have no arms? No, he has two fucking arms and two fucking legs and wings and so is just an ordinary dragon. He's massive, 20 feet tall with a eyes as large as a human but a head small enough to be cloven and hoisted by a man. Hard to square all that visually.
In any case, much of these plot points are to introduce us to Greenhands, whose birth as a full grown adult literally out of a split tree that was once Kith's wife Anaya is pretty fantastic. We can see the writing on the wall pretty early here, as Greenhands as the first-born son will slip into place ahead of Prince Ulvian in the line of succession, but Ulvian has other ideas. I won't elaborate on these, other than to say that whenever a skull is devastated by way of hefty dwarven hammer, I'm here for the long haul.
