Formal and perhaps a bit uptight, Credence maintains a degree of professionalism when first meeting people and through common interactions. Having been raised in a high-class family in Sharlayan, this would lend itself to a man of meticulous mannerisms and etiquette. Due to his work as a chirugeon and healer he often comes off as distant with his clinical approach and his expertise and know-how can come off as borderline prideful and prickly. Despite his attempts to seem nonplussed, the right teasing words or implied criticism can easily leave him ruffled - just be prepared to be met with an equally sassy or sarcastic remark. This often places new acquaintances at an arm's length, but if you find common ground with him and perhaps share a few drinks you'll find a wry sense of humor and confidant.
Credence is very goal oriented and will throw himself into his work to meet them - to the point of his close friends having to pull this workaholic away for some downtime and socialization. A curious soul with a thirst for knowledge; his nature demands a need to question, to constantly test the limits of his own understanding, to seek the otherwise unknown - 'Knowledge Seeks No Man' after all, and yet in seeking these hidden truths he finds himself adopting his own creed. Just expect a healthy amount of skepticism first.
Known as the 'Good Doctor', this is more applied to his skills and expertise than any moral alignment. He helps those that are in need, sick, or injured - it's not his place to ask questions and with the right amount of persuasion, can be convinced to turn a blind eye to any sordid business regardless of his occupation. Heavens knows, he's probably seen worse.
