This universe has a civilization of humans! And some other things. It's not crowded in the way Edda is but it's not just the one planet either. The humans might be easiest to start with. They're on that planet over there, it's not Earth but it has very Earthlike conditions and bronze-age humans living in cities and villages dotted across two large continents. Depending on how thoroughly any prospective visitors look they might find other things before visiting.
The Song of Annunciation is a crooning thing that is in fact nicely musical, and Allspeak handles fairly gracefully.
"Oh great one who has claimed this place, I am a visitor at the edge of your territory. I respectfully announce myself to the dragon who claims this land-" (-You can replace 'dragon' with their name if you know it-) "I am here openly, without stealth or trickery. I do not mean to intrude or insult; I shall not hunt your prey nor steal your things. Under the gaze of Father Sun and the by the Two Great Laws, I ask for parley and peaceful discussion so that our musics may both be heard-" Several verses that are just rephrasings of the previous parts, and then, "I shall wait here for a time, and if you choose to approach we will speak."
And also the much shorter Song of Peaceful Departure, "While I have announced myself, you have not come to speak to me. I respect your territory no less, and now I am leaving."
Oh fine, that's sort of covered by the first Shiny Thing anyway.
First; You must create. One day you will die, and your music will become silence. Explore, learn, and seek Treasure, and when you are ready, seek out others who are great, and create children to carry forth your song forever.
Second; You must destroy. You must kill and consume to survive, but take care to destroy in balance, never taking too many or too much. Destroy that which should be destroyed. Preserve that which should be preserved.
Creation and Destruction are both part of the Onesong, one leading to the other. To live without these truths is unnatural and wrong.
This is the fundamental truth of the dragons.
AHHHHHHHHHHHHHHHHHHH randomly appearing and disappearing nothumans!
(Later, she eats all her shiny things, storing them in her throat pouch and sneaking off in the night.)
Even with the Song of Annunciation in most places the dragons demand that they leave, or ignore them.
In one particular area, at the edge of a region that looks and feels magically... Odd... A red fox that looks slightly unreal, like a Maia who doesn't quite have their body down, addresses the visitor.
Who Is It Who Comes Forth? What new chorus enters the song, so familiar and yet so alien? Why has your arrival changed the music yet to come? Why do we-I-the forest-the mother wish to speak to you?
A minute later, a - very very large dragon, taller than some trees, strides through the forest, their branches smoothly moving out of the way for her to pass. She has an aura, a psychic power that washes over everything around her and infuses it. It feels - careful and delicate, as if she is keeping it as light as possible. Flowers bloom and plants perk up and sprout new growth all around her.
I am the one known as Allmother, o visitor. I am all but unique among my kind to tread so deeply the path of Compassion - so much so that my very nature has changed. I welcome you to this world.
Oh, to see new stars and meet new people, to know the Onesong is yet greater than before... You will avert the Grey Future, the path I thought inevitable that has been laid out before me for so many years. I do not clearly see what form the future will take, but a bright star shines, a ray of hope and the knowledge that my fears will not come to pass. Our symphony will not end. They are lost in a way, the tailless ones. They are lonely and suffering, like so many of my kin. Crowing with strength and pride, yet empty inside. You are not the cold ones, who could not comprehend. Who are your people, to explore new worlds? What drives them forth?
Prosperity. Opportunity. Fulfillment. Kindness. Reaching higher and onward. To the humans, prosperity means great cities of stone and metal, edifices of order where everything is just as they wish it. Their hopes and dreams burn brightly, full of joy and compassion and love. They do not realize the value of that which they are destroying, the great spirits of nature and the balance of the world being eroded into nothingness under the stones of road and city.
To the true children of above and below, shiny things are valuable, great treasures and fascinating secrets a thing of joy and contentment, and yet to the greatest among us, once we know our place in the world and learn of the vastness of Nature, the pursuit of adulthood is spiritual. To feel, to know on a level deeper than mere knowledge, to reach a greater understanding of the Onesong and become ever more, for stagnation is death. That is what drives the eldest of us.
They do; They seek togetherness and progress. They wish to build and grow, and not unjustifiably see the dragons as a great enemy, hostile forever and anathema to their aspirations. It pains me whenever anything must come into conflict. I desire to see suffering's end, though it is impossible. Perhaps I am a coward and a hypocrite for having ended it in myself. I could not stand my own nature, and changed it. All life has become one in my domain. I am the trees and the ants, I am the rabbits and the foxes, I am the soil and the air, they are all me. I regret this in some ways, but what has been done cannot be undone.
There are some gods in my world who do something like that, they put themselves deeper and deeper into a grove or a river or a flock of geese until they're effectively one and the same.
We too want to end suffering. I think you could help us, especially if you were willing to speak to other dragons on our behalf. Many of them ignored our visitors and we aren't sure what else to try when the Song of Annunciation and offering shiny things didn't work.
That bears some resemblance to what I have done, though I could not take the final step.
I think some will speak to you on their own time. Dragons move slowly by the pace of humans, those of us who are not children. The other elders will call a Grand Moot in time, a meeting of all adult dragons to discuss the future. Even if you had not arrived, humanity is becoming more alarming to them.
I will be willing to send myself forth as envoys if there is something productive for me/us to discuss. My kin will not accept to allow the humans to continue conquering and expanding. They may not even be willing to accept their current extent, as in the mere last clawful-of-clawful-of-clawful of years so much territory has been lost and so many dragons killed.
The spirit of the Great Green and echoes of the Onesong have settled deeply into this planet. The weight of history and the spirits of so many creatures infuse it deeply. Anywhere else would not be the same, and our pride, that claw turned upon ourselves, will not allow us to retreat without a challenge.
