Midas
Anarchosocialist dragon alchemist character description
Whoever came up with transmutation was extremely unlikely to have expected that anyone would ever use it the way that Midas ended up using it. It's not just the fact that he has no need to keep an alchemist's furnace in the cave that serves as his residence because he's developed the ability to use his very own fire breath as a makeshift substitute for one. It's what he chooses to use the crude raw materials that he turns into gold for that sets him apart. Even though his fire technically temporarily creates gold, identical to all other gold right down to the molecular level, as far as it relates to his long-term goal, Midas has taken the idea to burn $1,000,000 to run with it much further than it had ever been taken.
Knights who walk into his cave and point their swords at him saying "I've come for your treasure hoard, vile fiend!" don't quite expect him to answer "Would you like a wheelbarrow to carry it in, or did you bring your own?" They don't know how to react and stammer for a bit and he taps his foot with his head tilted and his arms crossed. "I can load it up for you if you want, but make up your mind about the wheelbarrow, mmmkay? Haven't got all day, y'know."
Some of them, as befuddled as the offer makes them, decide not to look a gift dragon in the mouth and to take it anyway. Some think he's lying and, expecting foul play on his part as they try to leave with the treasure, decide that they should try to kill him before doing so anyway, just to be on the safe side. Some of them decide to try to kill him because they think that if they come back to the villagers and king with a treasure and no dragon's head to go with it, they're only going to look like they've just robbed a rich noble and made up a story about it. And some of them decide to kill him because they're really only using the treasure as an excuse for their predilection for killing dragons anyway.
Unlike what most dragons are known for, Midas has no interest in gathering as much gold for his own treasure hoard as he possibly can. He just doesn't understand what that's supposed to prove or accomplish. The reason for which the king sends knight after knight to kill him is that what he's really up to is much more dangerous to the king than that. Midas didn't only learn transmutation to bribe the occasional knight with much better than what the king is paying him. He sees that the peasants struggle with miserable poverty while the king has more gold than anyone could ever possibly need, and since all of his own needs are already well accounted for, the next step in line for him, the way he sees it, is to devote himself to doing everything he can to make sure that the needs of others will be accounted for to the same extent. His broken bond to a former dragon rider has taught him to hate servitude and hierarchy above all else, and he makes it a point of honor to break them wherever he finds them.
The king first noticed that the peasants were no longer coming to him for donations that they'd owe him ever-increasing debts for, yet that their farming equipment seemed to have been getting better all the time without any members of their family having to starve for it, and without having had to sell any of the hard-earned products of their labor for it either. He tried to raise taxes to lower their conditions back to their original level, and they managed to somehow pay his newly raised taxes in full without suffering a drop in the level of their quality of life for it. He sent knights out to investigate, and the knights, having been paid twice as much by the peasants to say so as the king had paid them to investigate, came back with innocent-sounding reports that there was nothing new under the sun for him to have to worry about. He sent some of his most loyal and skillful spies, and they came back frightened that the peasants had been able to afford to purchase defensive weaponry that rivaled what the king was buying for his own elite knights.
This displeased the king a great deal, but he wasn't sure of what to do about it.
Midas' long-term goal is to destroy money, plain and simple, by giving everyone so much of it that they'll be forced to realize that it'll have lost all meaning, so that people can finally go back to doing what they need to do for each other for the right reasons which they should have been allowed to do them for to begin with. He wears a white jerkin with a gold cross on it, wields a thin but solid single-handed sword with an elegant fencing style, and completes his exquisite knightly manners by throwing in the occasional irrepressibly wide toothy grin. He rescues damsels from knights and knights from damsels, and ends up needing to be rescued from a damsel by a knight, and from a knight by a damsel. His allies sometimes join him because they've been rescued by him, sometimes because of the incredibly high salaries he pays them, and eventually because they end up understanding his cause and sharing his belief in it.
"I don't think you realize how serious your situation is. I could buy and sell your entire army in a heartbeat. I'm afraid you're not going to be able to throw money at this one. Your Majesty.
