I'm running a world where I combined 2 different campaign ideas.

The first is about being a group of kobolds or other small races that are part or a tribe that is serving under an Ancient Red Dragon.

The second one is about the end of the world, post-apocalyptic, where the tribe lived 50 years underground and in the meanwhile 50 years of destructions growing smaller and smaller happened, where almost every civilisation fell.

It's been going on for over 2 years now. They are now trading mushrooms to a neighboring Ancient Gold Dragon because his daughter loves them (on a lucky die roll) that I called Gigastrax, and where my players immediatly jumper to Gigachad.
