Ernis Federyc is the first of various protagonists I have planned for an upcoming fantasy/mystery series I have received exorbitant help for from this very forum that emphasizes the corruption of information relating to events the audience has read of to use themes related to the distortion of history acting as a means of foreshadowing and world-building. The first main protagonist is a notable figure among people in their earliest stages of cognizance, living during an early-enacted period of Enlightenment onset by the previous presence of a humanity-threatening elongated winter as a means of adaption so to use the new focus on knowledge to learn about means of survival. The fixation on knowledge and mental exercise has persisted generations beyond the elongated winter, with the systematic interaction of every human being well defined by members of a new "intellectual" class, who are often picked for mentally demanding jobs, while those belong to a "hefty" class, both denoted by differing attire, are often picked for more physically demanding jobs. Ernis Federyc is an author of fictitious works, an occupational field that has few members thanks to the fixation on the current world and understanding it to the greatest degree. Ernis is wholly responsible for popularizing fantasy in this world and his books are held as high in regard as those of exceedingly important knowledge, if not more; because of the few copies of his books that exist, they're often traded in exchange for some food. He's also responsible for popularizing cross-class recreation, creating forms of competition and games that often are capable of accommodating members of either skill class. Ernis rarely leaves his house on the outskirts of the small human community, living perpetually distasteful with the erratic nature of humanity. Though I have 9 paragraphs spanning the description of his personality in a notebook, the gist of it is that he is clinically dependent upon order and systematic interactions and possesses a controlling nature as a result. He finds himself only accepting of the individuality of his sole friend Reginald Belefontaire merely because of his interestingly unconventional mind that exists as orderly and consistent in spite of that. He dislikes losing control of situations, which is why he willingly sacrifices sleep to continuously pour himself into his work which he does compulsively as its cathartic and satiates his demand for control. The presence of Reginald is cathartic and also prevents him from having fits of anxiety and/or angry for the most part, and so he only indulges himself in human interaction in the company of Reginald. However, even then, he is still sometimes capable of fits of anger thanks to his compulsory demand for order and control. How could I express this in the story with this causing the friendship between Reginald and Ernis breaching before I find it could advance the plot at all?
