Dnd style dragons come out of the egg knowing languages meaning that they had to learn it somewhere. I'm not interested in that. What I want to know is, that assuming Dragon lullabies are like human lullabies, what would they sing about?
To clarify most human lullabies are about getting the baby to quiet down and also the scary parts of the world. There's more articles about it but here's a good example: https://www.bbc.com/news/magazine-21035103
There's also a national geographic article that was good: https://www.nationalgeographic.com/magazine/article/what-the-lullabies-we-sing-to-our-children-reveal-about-us-feature
What would a dragon be scared of, for the babies or the dragons, enough to sing to their eggs while brooding over them? I'm mostly interested in Ice Dragons if you want a specific type of dragon but any dragon in general will do.
In my world sixty or so years ago the air became poisonous, the poison part is just hand waving because nobody knows why other then it is in the story, to sapient creatures, dragons included, other then that it's a vaguely earth centric world up to the 1970s. After that it diverged into most people dying and people, including dragons in disguise, making out living in various manners. The three largest ones are giant walls of stone that happen to block the poison in the air, the mining quarry that mines said stone, and one place that manages to pull the posion out of the air.
To clarify the dragons are dnd style in an earth like world up until the 1970s after which the timeline changes.
