This design is for the people who have to explain their disability multiple times a day, are constantly facing barriers to accessibility, receive a barrage of advice about how to get better, are repeatedly told "but you don't LOOK sick," and/or are gaslit by doctors and other professionals.
"Fireballing the next person who says I don't LOOK sick." You've heard of a Chronic Illness Warrior? Meet the Chronic Illness Wizard. Even these wizards don't know what's wrong with them, and they know everything.
"I smite platitudes." You've heard of chronic illness warriors? Meet the chronic illness paladin. These paladins may never have Divine Health, but they definitely wield righteous anger against unhelpful sayings like "everything happens for a reason."
