Da_GutI keep thinking about a younger copper dragon. Loot poor at this stage of his life and with a not so great lair.
He seeds the hills around with shiny stones - small boulders really. But they glint in the sun.
And he props up large stones in what looks like some obscure signaling pattern.
He is just curious and wants to see what is attracted to this. Perhaps it will be somebody who he could trade jokes with.
