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.

The rat clans are not a proud people. Pride is foolishness. We live half-blind in the dark, always hungry and always searching. We are one and many - what one of us knows, we all know, linked by the essence and spirit of our Love. What one of us decides, we all decide, a family that knows each other better than ourselves. Though we are small, we are careful and observant and clever. No trick or distraction is beneath us. We use the small paths others cannot access, we use our secrets, we use our numbers, we use even our teeth and paws if we must. Hunted by cat and hawk and hunger, the rats yet survive.
