It’s not on the wiki, as I said - it’s in the actual novel The Great Betrayal. I literally just read it, and I have it here before me.
Gotrek Starbreaker was Snorri’s father, not his son - I’m talking about Prince Snorri Halfhand, who was never king.
Some quotes from the book:
(Morgrim speaking to Snorr)
Snorri stood up too. ‘It is reckless to do nothing, cousin. The elgi have enjoyed our understanding and flouted our hospitality for too long. We must show them who the true lords of the Old World are. My father will declare war. What other choice does he have?’
‘And if he doesn’t?’
Snorri’s eyes were hard as granite. A harsh wind tossed the curls of his beard, making him appear even more belligerent.
‘Then I shall declare it for him.’

(Priestess of Valaya to Snorri)
‘Then don’t be so pig-headed, you stubborn, obstinate fool. Look beyond your own selfishness and see what this will mean. If you make war on the elgi, you will invite devastation on us all and estrange your father into the bargain. Is that what you want? Is that why you are here?’
‘It’s my destiny.’
‘To kill wantonly to satisfy your need to be honoured by your father? Do you think he will clap you on the back and tell you how proud he is of you for defying his will? He will not respect you for this. He will despise you for it. So will I,’ she whispered.
Snorri had no answer. In his heart, he thought what he was doing was right. Some small part of him knew it was to serve selfish needs, but he assuaged that guilt with the certain conviction that he was acting on behalf of the greater good. Confronted by the hard truths from Elmendrin, he wasn’t so sure.

‘It will do no good,’ said the prince. ‘None of this will. I meant what I said, war will come. Dawi and elgi are too different, it’s only a matter of time before we start killing each other for real.’

(Morgrim to Snorri)
‘You want to kill the elgi, don’t you? It’s like you hate them, Snorri, and don’t care what you have to do to vent the anger that comes with it.’
Again, Snorri fell to silence.

(Morgrim and Snorri are offered a ride by an Asur ambassador, notably this is prior even to any Druchii attacks being known of, so they are purely allies at this point).
‘Hail, dwarfs of Everpeak,’ he said, using rudimentary Khazalid and referring to Karaz-a-Karak by its common name.
‘State your business, elfling,’ Snorri demanded.
‘I am Imladrik of Caledor, Master of Dragons and Prince of Ulthuan, Lord of Oeragor. I bear you no ill-intent, lord dwarfs.’
Despite the offer of peace, Snorri was pugnacious. ‘Dragon master, eh? I slay dragons, elfling.’
Imladrik raised a gauntleted hand. The knuckles were fashioned as scales, the fingertips like talons.
‘I am an ally to you. I mean no harm,’ he assured them.
‘Be calm,’ Morgrim hissed to his cousin through clenched teeth, looking sidelong at the creature drooling sulphur and smoke.
Snorri hissed back, ‘I won’t be cowed by this elgi and his beast!’
‘No, but you may be eaten, cousin!’
‘A lot of titles for an elgi,’ Snorri scoffed. ‘I’m surprised you can remember them all. And you should be more concerned about who wants to harm who, elfling.’
‘I am Prince Snorri Lunngrin of Karaz-a-Karak, heir to the dwarf kingdom. You are upon my sovereign soil, elgi.’
Imladrik bowed, betraying no hint of reaction to the goading Snorri was attempting.
‘I meant no offence, my lords. Through the storm, I saw travellers on the road. Once I realised you were dwarfs, I decided to descend and see if I could offer you a ride. It is a long way back to Everpeak, and since it is where I am bound…’
Morgrim turned to his cousin and whispered, ‘I have never ridden on the back of a dragon.’
‘With good reason.’ Snorri looked askance at the beast. ‘They are fell and dangerous creatures. Not to be trusted, much like their masters.’
Elves were possessed of incredible hearing and Imladrik had heard every word exchanged between the dwarf nobles, but if he thought anything of it he did not show it. He merely smiled impassively and waited for them to make their decision.
