The Land of Nowhere

Do you ever wonder what happens to lost people or animals? Not things, thankfully; after all, we all know the left socks are stolen by trolls.
But what happens when a pet goes missing, or a man vanishes?
Well, it's simple, really. They end up Nowhere.
Nowhere has no beginning, or end. It is an expanse of beautiful land that ranges from gentle woods to rolling fields, with rivers, streams and lakes. All those who are lost find themselves in Nowhere.
In Nowhere, there are two constants:
One are the Beasts of Time. Terrifying creatures that can be large and destructive, or small and sly. If they manage to catch their victim and drag them away, the unfortunate soul is lost forever, forgotten even from the memory of those in the real world.
The second constant is a woman by the name of Rebb. She is the antithesis of the Beasts of Time; they attack and destroy, she protects and creates. It is her sworn duty to protect the occupants of Nowhere from the Beasts of Time, and she will do whatever it takes to achieve that goal. A frightened child is easily comforted by her gentle voice, while a stubborn fool will get a firm reprimanding and what is typically called 'tough love'.
Rebb is as wild and incredible as the land of Nowhere itself. She is an enigma like the world around her, both charming and fierce at the same time. Nobody knows how she got to Nowhere, or who gave her the task of protecting the people and animals that arrived.
The only certainty is that as long as the Beasts of Time exist, she will be there to stop them.
((Please note; because it is the Land of Nowhere, characters from all genres/time periods are acceptable))

People from all times, eras, and worlds can get lost. When they do, they find themselves in Nowhere.
