Humans have been handed a lemon, and you have 2 weeks to make lemonade.
I have a magic system based on the Opponent Processes model of vision. This magic system has three competing pairs of colors: black and white, red and green, and blue and yellow. These colors can be mixed when casting spells, but you can never mix opposing colors. You can cast a "purple" spell (Red and blue), or a "light blue" spell (Blue and white), but never a "red-green" spell, because those are opposing. It'd be like trying to mix a positive and negative electric charge.
However, this world has both Humans and Faeries in it. Faeries, being smaller and more numerous than humans, can band together to manipulate magical fields at a finer detail than a single human can, allowing them to interlace spells with sharper gradients. The result of those interlaced spells feels like the apparently vibrating boundary between red and green lines that can make it hard to look at badly designed Christmas cards.
I don't want Humans to be obsolete, but magic is a major part of this universe! A leading species without magic will simply not be a leading species for long. Help me keep Humans relevant! So here's the question:
What's the most parsimonious justification for how Humans can continue to thrive despite Faeries' finer control of magical color gradients?
I'll choose the best answer some time around November 22, based on these principles that follow from Occam's razor:
- Succinctness is a blessing. The fewer details you have to bring in the better. A world with multiple color of magic, 13 competing races, and a steampunk technological bent is beautiful and fun, but if the same problem can be approached with "a world that has benevolent aliens visiting it," there's something to be said for that. Keeping the answer as close to the question as possible should be rewarded.
- Impact is powerful. Answers which satisfy the question with a powerful resonance, one that begs the next reader to dig into the effects of your solution, inspire more creativity in those around us. Feed on creativity!
- I'm not just looking for a simple solution here. I'm looking for a creative approach which not only renders the issue raised by the question moot, but makes it look like the author started with a bigger problem, and this entire issue was the solution to it. It should seem like this question brings closure to something profound, rather than raising questions. In order words, I want something that feels more like what members of a literary analysis wiki call "justification" than a "handwave".
