Currently undergoing rewrite, because a lot of the sub-plots here were very convoluted and difficult to actually express. I took some time off and finally thought through what I was writing, so there's a much neater plot going on. New story will be posted soon under the title 'Perceptio'. Perception comes from the Latin word perceptionem, and that word's nominative form is perceptio, which is where the title of the rewrite will come from. Thank you all for being so supportive and so patient with me.
