One of the earliest images I had in my head for this universe was of a stylized, anthropomorphic sun, blowing dandelion seeds across the universe. I think this pretty much nailed that.
My first vision was of a stereotypical puffy-cheeked “old man sun”. Sis lobbied to “make Sol a girl 2017,” but you know, the sun is really the quintessential agender, so a nonbinary sun it is.
My mental image also involved cheeks puffed out like a trumpeter, but that’s not how people blow dandelion clocks. I don’t regret the changes in the least.
