Well, this is quite a coincidence. I was just dreaming about a DNDesque adventure party story last night. I think the priest should stay a good guy, in to many stories the church/healer is secretly bad and it is actually rare for the them to be good nowadays. Of course I am slightly biased as I want the darker member of the adventure party to be a character I was dreaming about lol. For the DNDesque story I was dreaming about I was thinking 2-4 authors get together and plan out a rough campaign the group would follow, then write the individual stories for the party members. Each having their own goals but find themselves together after a shipwreck.(I know a popular DND trope.)
Having a good priest with a clear goal would give the party a direction and something to travel to. The character I was dreaming about would be the total opposite to the priest, instead being a pirate wanted by the navy and other pirate crews alike for his brutal actions of raping, pillaging, and murder. Of course I would have to tone down the pirates story immensely to fit Choya's guidelines but I think I could probably do it.
On the priests journey to save another group of adventures he hopes on a boat which later capsizes, either due to weather or an attack from pirates/navy. When he awakes from the shipwreck he is greeted by the survivors, one being a pirate, the others to be determined. After the shipwreck the priest is worried about making it in time to save his friends and asks the group if they would travel with him to help save them. They agree the pirate mainly not caring where they go as long as it isn't by sea anymore.
In the introductions for each character before they set off the reader learns more about them. The priest introduces himself first giving some backstory and his goals. The pirate introduces himself next as a ex-navy captain who had a disagreement with the navy and quit, he was on the ship to leave his life at sea behind and to start over when it made land. Proficient in sword play and shooting his pistol. He also throws a small comment at the end that he doesn't do well around blood, shouldn't be a problem during battle but after he would need sometime alone to regain composure. Following are the rest of the party.
They continue on their journey and after every battle the pirate seeks his alone time for seeing blood, the priest is good natured and suggests healing the pirate and taking a closer look at his problem. Shaking off the priest concerns he tells the priest that it isn't something the man could fix. The pirates problem with blood isn't a mental trauma or a real problem with his body. No, at the sight of blood he becomes increasingly aroused, due to his pirate days of raping and pillaging, his body has become conditioned to exploded in lust at the sight of blood. Every time he sees a drop of blood, smells its heavenly iron scent, he is remined of his pirate days the woman and men he had bedded as he and his crew pillaged towns.
Sometime the pirates urges become to much and he will purposely knock out an enemy he was suppose to kill and hide their body during combat so on his alone time after battle he doesn't have to resort to his hand. If it happens while they are passing through a town he will try and find a prostitute to satiate his lust or he may just slip into his old ways taking a random person off the street.
The pirates journey with the party will be a internal battle with himself the whole way, on one hand he has his every growing lust and desire to leave carnage in his wake like he is familiar with. The other is his desire to lay low and not leave a trail of bodies his pursuers could follow. Along with trying to hide his actions and past from his traveling partners who are growing ever so suspicious of him. Maybe one of the party members secretly follows him during one of his alone times after battle and catches him masturbating or even worse defiling one of the enemies from the previous battle.
Or they follow him after a bar fight that drew blood while in town, the priest staying behind to heal the injured while the two party members slip out unnoticed. The other party member suspicious of the pirates story follows him in secret wondering what he does every time he encounters blood. After following him they see him falling into the arms of a prostitute or much worse attack a townsfolk. Do they attack him and stop his assault or do they watch for some reason? do they like to watch or are they just gathering information to latter use as blackmail?
I'm running out of time to actually write something for my current stories so I will have to leave it here for now. However as a final note I would like to mention the pirates encounter with a siren who sings of the thing he most desires one day as the party travels together by boat. The siren sings to him of a meal he had when he was a child the best meal he had ever eaten in his life, however being a man familiar with the sea he doesn't fall for the sirens lure. Instead he interrupts the sirens song with a warning, if she continues singing and he follows their voice and they don't have what she promises in her songs he would show them the second thing he desires most(rape and murder).
The sirens song start up again after a few minutes of pause... Do they think he is bluffing he wonders, before telling the party to stay on the ship as he is familiar with how to kill sirens, then he swims to the cove with the sirens voice. He had warned the siren about singing again and if she truly doesn't posses his greatest desire then she will pay the price by satisfying his second.
