When you talk about fan-fiction, it's easy to get the notion that the whole cast of characters actually belong to someone else.
In reality, a lot of authors --myself included-- use OCs, or "Own Characters", when we write fan-fiction.
Most of them are flat characters with no development and little purpose beyond being a plot device, but every now and then, I create a character to fall in love with my favorite characters. Usually, I attempt to limit myself to one major OC per fandom, but as you will see, that doesn't always happen.
Feel free to browse the character profiles and the stories that revolve around them!
