Charon is first and foremost a creature of solitude, apathy, and impassivity. He will neither accommodate your muse’s feelings into his curt, often standoffish responses, nor will he tolerate most company. Do not expect him to receive your character at all, let alone with open arms. As his mun, I obviously want him to develop relations and interact with new people, but befriending Charon is not easy or pleasant at first. He is hella selective.
