Unfortunately, Poppy doesn't really know much about the elves beyond the tales told in the Shire
"Certainly, I will convey well wishes from your entire party," Lindar said, bowing, "As soon I find the opportunity. Come, now! There is much to see."
Lindar, over the next days, takes you on multiple trips through different parts of the halls, and you have the opportunity to meet a lot of elves. The elves themselves are polite, in a sort of pulled-back, suspicious way. Nevertheless, as they see more and more of you, they open up somewhat.
Yet their opening up reveals more of an inner somberness and tension than any sort of joy. Or at least, not much joy.
Lindar takes you through the system of caves, which he explains were a natural formation, in which Thranduil lived going as far back as the First Age of Middle Earth. The caves have been worked on by both elves and dwarves since then, though not in a great many years.
"Is Thranduil seeing anyone today?" he asked the Sentinel who stood near a large and intricately wrought gate of silver, which barred the way to stairs leading to a high platform, which Lindar explained was Thranduil's "throne room."
The Sentinel shook his head. "I'm sorry. He is not. Nor has he informed us of plans to open the gates anytime in the next few days."
Lindar nods respectfully, and leads you on. He shows you the many levels of the halls. Marketplaces, homes, barracks, musician's halls, crafthouses, cellars, and much more.
Until at last, on the morning of the third day, he arrives in the company of Baldor and Belgo.
"We are ready for the next leg of our journey," Baldor says, with a smile. "Will you all be prepared to leave within the hour?"
