There's an amphitheater, a place where a hundred of the stone walkways twine around to create space for a hundred thousand people to sit in close proximity, and someone is giving a lecture or a demonstration at the base of it, the seats closest to him filled with eager, tiny, bearded Dwarf-children.
And they spiral down, and down, and down, past waterfalls and egg-sized gemstones left half in the rock and halls of crystal. Everything grows gradually more ornate and more perfectly maintained and the clang of hammers fades behind them. "People say," her guide says, "that we only have a council instead of a single King because there were nine winners of the competition to design the throne so we couldn't just select one person to sit it." And they push open the doors to reveal, indeed, nine thrones so elaborate it would be hard to choose between them, and nine squat bearded people sitting them.
And Loki flies home and explains the runey brick thing and sends an elfbird to go tell whoever's building that eight-pointed city, and their host, and their cousins' host.
Oh, is that what happened. Man, what a dick that guy is. Well, she has the functional version, she saw it glow and everything. Come on, folks, let's get a perimeter up so nothing can sneak by. Except you, messenger elfbird, you're going to go make sure the good news gets where it's going.
That works as warning but not as deterrent and not as orc repellent. She recommends they build it higher, but they do have other things on their minds and realistically it's not going to be a twenty foot wall up in a year.

"I keep forgetting your name," she tells the bat. "I don't know why, it just slides right out of my head."

Sauron says you can have five years' truce if you come work in Angband, with the hopes that once you see each others' projects you can discover whether there are others on which you have ground in common, and if you name your terms more specifically he'll send proposed drafts for the wording of an oath. He also says that he's enjoyed the last few years tremendously. He also says that, realistically, if you can't think of a way to find common ground in five years, he's at that point going to kill you, albeit regretfully."
"Well, in that case it seems like a bad idea to plan on being somewhere he can get at me in five years' time."
"Does he seem to be envisioning that I will be socializing with him much in Angband? That would probably be more of a drain than the suicidal Quendi because he can manage 'interesting conversationalist' and has demonstrated mastery of getting under my skin."
"I should probably consult with a bunch of people on this one. Last time I thought about making a deal with him somebody else noticed flaws I didn't. But thank you for conveying the message."
...She thinks somebody else might have better luck with Ulmo than her, but if somebody wants to be birded and sent to plead with Ulmo she can spare them.
