The story of Stiny and Largesse was an allegorical one, and a love letter to my first crush. The story was basically of two worlds of different sizes overlaid onto each other in the form of a paradox.
Stiny's world was a vast open grassy field with a bunch of low-lying berry bushes only barely up to his ankles. In this world, the brown fox was completely alone aside from his Creator occasionally walking and talking with him, as he was surrounded by insects, not fellow animals. The only larger animal was the Creator himself, a lion.
In Largesse's world, she was born into a complex tribal society of wolves and other creatures in the seemingly endless forest, who ate very large fruits off of very large trees. She was a runty wolf, even in adulthood less than half the size of any of her siblings. The only smaller animal was her Creator, a ram whom her pack rejected in deed if not vocally but with whom she had a relationship.
Anyone particularly familiar with Christian symbolism will recognize that the sheep and the lion were of course one and the same. One day, the she-wolf was brought to Stiny's field, and filled with wonder at the openness of the sky and the greenness of the ground, feeling the dew on her feet and meeting someone even smaller than herself - though to her perception, still larger than the sheep she'd followed there. Stiny was completely over the world with joy at having a companion - she was not as large as the lion who was to this point the only other living, speaking being he'd ever encountered.
When visiting the forest world and meeting Largesse's family, Stiny was made to wrestle some of her older brothers and he won, unexpectedly. He had a little hesitance regarding how much bigger they obviously were, but still tackled the problem and surprised everyone.
A lot of things happened in this story, including her pack trying to ritually sacrifice her to a dragon. The dragon was Stiny, as while he was a fox in his own world, he was a gigantic dragon to theirs - and likewise, while they all perceived themselves as mammals in a forest, in his world they were insects scurrying about in the grass; Largesse was a blue moth. Both main characters would occasionally be tempted or harassed by an evil lioness wearing a fake mane. Sin and redemption. Eating, drinking, and being merry (and getting married). Stiny very gently pressing his toe down on a bad guy and crushing him to death.
I've made some occasional references to this story in my other works since then.
Largesse was obviously made large and named after that size focus because I've ALWAYS had weird hangups about size differences in romantic couples, and especially when I was younger put a lot more emphasis on females as larger than males. This was partly out of being browbeaten by the culture I grew up in into having poor self-esteem on account of being male, and somewhat for crude and mechanical reasons that wouldn't even have worked for this couple because she wasn't ENOUGH bigger than him for that.
Stiny was named as a portmanteau of "small tiny" for the same size related psycho-pathology I was suffering, and as a reference to a Strong Bad email: https://www.youtube.com/watch?v=CzgaFc3JAl8
