Calentauriel sought one who had seen the wreckage of Isengard, and who would be willing to tell her of their experience. Eregiel accompanied her sister to ensure that she was not overly bothersome. Those they found who had seen Isengard in its ruined state were either occupied preparing for their return to Edoras or were taking rest before their departure. At last they found upon Éomer, Third Marshall of the Riddermark and, since the death of Prince Théodred, King Théoden's heir.
Courteous introductions were made. Then, not wishing to occupy too much of Éomer's time, Calentauriel began her questioning. 'Lord, is it true that Isengard has been overthrown?'
'It is true,' the king's sister-son answered, 'but it was not accomplished by the might of the Sons of Eorl. When the king and his guard, accompanied by Gandalf and his companions, rode to Isengard to speak with the wizard Saruman we found the fortress had been drowned and its walls greatly damaged.'
'If not by the Men of Rohan, lord, who then accomplished Isengard's ruin?' Calentauriel inquired.
'Isengard had been thrown down by the shepherds of the forest, Ents they are called, led by one called Treebeard,' Éomer informed the inquisitive Elf. 'I reckon that you are curious to see it for yourself, lady,' Éomer continued. 'I strongly advise against it. The Ring of Isengard is in a very precarious state. It is not safe even for the mighty Elf-warriors of Dwimordene.'
'Thank you, sir, for all that you have told me,' Calentauriel said. 'Despite my great curiosity my sister and I will not be returning to Isengard.'
'Of this you may be assured, lord,' added Eregiel who had remained quiet throughout the discourse. She quickly curtsied to Éomer, then took her sister's arm to lead her away before she could say or do anything foolish or embarrassing.
'Why the haste, nésa?' Calentauriel asked Eregiel once they were out of earshot. 'I was as tactful and courteous as anyone could have hoped for, even our sister Thibinoriel.'
'You were indeed, nésa,' replied Eregiel, 'but I did not wish to overtax Éomer's patience nor occupy too much of his time. In case you had not noticed, these Men are preparing to ride to war.'
'All right,' Calentauriel said resignedly. 'I suppose you have a point.' 'As usual,' Eregiel thought but did not say aloud.
