Can you expand the setting by adding more detail, and also make it darker and more brutal in tone? I am looking for mature medieval fantasy, as opposed to generic fantasy. Also, Please provide three more characters that are less typical in fantasy settings.
Sure, I'd be happy to expand the setting and make it darker and more brutal. Here's an updated version:

Setting: The game is set in a dark and dangerous medieval fantasy world, where magic is both feared and revered. The players journey through a harsh and unforgiving landscape filled with mythical creatures, ancient ruins, and powerful magic. The land is plagued by war and conflict, with kingdoms vying for power and control. The dungeons where the crystal is said to be hidden are known for their brutal traps and ferocious beasts. The journey will be treacherous and the players must be prepared for the worst.
