In the night, feverish, he thought he saw the water return… all that flat sand plain changing back to the sea it had been, and the stone boat afloat on it. Under the surface, he saw Rose and reached down to her. She took his hand, pulled it down into the stinging salt water, pulled the whole boat across the sea…
– Brier, Seeker's Mask, "Part V: Mount Alban", VII
With the rest of that command, Rose served under Torisen at the Battle of Urakarn, in the vanguard, though he urged her not to. They were captured and tortured. Rose escaped with Torisen, Harn, Rowan, and Burr. They fled into the Wastes, into the Great Salt Sea. Rose stumbled into sink-sand. The others continued, and that night slept in an ancient, petrified boat from when the sea had been liquid. That night, the sea turned back to water, and Rose reached up out of it, took Torisen's hand, and pulled the boat across the sea, to safety. When the survivors got back to Kothifir, Torisen, was sick, and his hands infected, but he didn't sleep until he'd told Brier how her mother had died.
Caldane considered this betraying the Caineron to the Knorth, and for that he carried his grudge against Rose on to her daughter Brier.

↑Bound in Blood, "Chapter VIII: Glass of a Different Color", I — " 'I wonder how my great-granddaughter Brier is doing.' […] 'Wait a minute. Brier Iron-thorn is your kin?' 'Not exactly, since we only trace bloodlines on the mother's side.' "
↑The Sea of Time, "Chapter XIII: Dreams and Nightmares", II — "No one but Krothen believed in the existence of the mysterious assassin who cast the shadow of a wolf. […] the new king-to-be had insisted that he, Torisen, investigate. To do so, he needed help. Harn had assigned him eleven Kendar. […] Tori suspected that one, Rose Iron-thorn, a Caineron yondri-gon, was Genjar’s spy, but like the others she had served as a guard in Kothifir during times such as the recent unrest and so had special knowledge of the city."
↑The Sea of Time, "Chapter XIII: Dreams and Nightmares", VI — "Tori’s small command […] had insisted on joining the vanguard with him, although he had tried to talk them out of it, especially Rose. 'Think of your daughter,' he had urged the Caineron. 'This could be a suicide mission.' Iron-thorn had only shrugged."
↑The Sea of Time, "Chapter XV: Winter's Tales" — " 'That you, Harn, Burr, Rowan, and Rose Iron-thorn fled into the Wastes, found a stone boat, and sailed it across the dry salt sea, yes,' "
↑Seeker's Mask, "Part V: Mount Alban", VII — " 'They had escaped from the dungeons of Urakarn and were fleeing across the Dry Salt Sea. Rose stumbled into sink-sand. […] At dusk, they found the petrified remains of a boat and collapsed into it. In the night, feverish, he thought he saw the water return… […] the stone boat afloat on it. Under the surface, he saw Rose and reached down to her. She took his hand, pulled it down into the stinging salt water, pulled the whole boat across the sea… in a dream, he thought, born of fever; but in the morning there they were safe on the northern shore,' […] 'Torisen told you that story, didn't he?' […] 'Dazed. Sick. […] he said he couldn't sleep until he had told me how my mother died.'"
↑The Sea of Time, "Chapter XXII: The End of Many Things", III — " 'Rose Iron-thorn never swore to the Knorth.' 'She might as well have, after what happened at Urakarn and in the Wastes […] Lord Caineron never forgave her for that, or you, by extension.' "
