Sir Archibald's Quest

The Von Dornm family made their fortune after discovering various rare components in the mountains surrounding their estate. These components can be refined into a drug known as Sundrop.
Sundrop is a bright/yellow orange liquid naturally incandescent, as if it was a liquefied ray of sunshine. Originally used as a magically synthesized antidepressant. Sundrop when consumed tricks the user into believing he is happy as it quite literally gives them a warm feeling. Over usage may leave the user feeling withered between uses, as their dependency has rendered them unable to produce dopamine and serotonin. Overtime users also commonly begin to build tolerances to Sundrop, requiring greater quantities to be consumed to maintain the effect. Overdosing on Sundrop causes feverish conditions, as the drug radiates through the users veins, ultimately burning them alive from the inside out. 
To produce the drug 3 villages were built on the mountain slope near the Von Dornm estate, these villages focus on different parts of the drug synthesis and use the river as a means to deliver cargo between each other. These villages are consumed by the drug with almost all of its denizens being addicted to Sundrop, many of them succumbing to overdose oevre the years. 
As Christmas approaches and Santa sees the all the village once again in the naughty list he decides to finally take action. Three weeks before Christmas Santa sends out 3 plagues to stop the drug production. However Christmas is a very lucrative time for the Von Dromn and the current head of the family, Sir Archibald. wont stand by as his profits are halted.  
As such Sie Archibald calls 5 carefully picked adventurers to help clear the plagues and restore the villages to full functionality before Christmas. These adventurers are contacted via letter, which reads:
Dear Mr
Sir Archibald Francis Earl Von Dornm summons you to his estate with the utmost urgency. You have been selected for a special task and must present yourself to the Von Dornm estate in the matter of three days. After the task is completed, you will be rewarded 10 000 gold pieces as well as any items you retrieve of interest. The currier will escort you to the estate.
Regards,
Sir Archibald Francis Earl Von Dornm
The letter reaches the adventurers safely and all the recruited assemble at the Von Dornm estate by the 13th of December. These adventurers were:
Grizzler, a Goblin Invoker
Faust, a Human Physician 
Mr.Convinient, a Human Rogue
UnnieBunnie, a Gnome Rogue
Lorian Stillwater, a n***** Human Paladin
After arriving to the estate and following a quick intruduction the adventurers accepted the mission and were gifted with a magical item to help with their mission. As a means of transport the S.M.R.S or Super Mega Race Sleigh was provided. This highly maneuverable and deadly fast vehicle was of course piloted by the least mentally stable member of the group.
After a quick 5 minute journey the froup found themselves in the first village, the village seemed quite and empty with all the houses closed and no one to be seen on the streets. The floor was litered with gingerbread men and at the center there was a large gingerbread house. Faust picked up one of the gnbread men and took a bite being imediatly imoberlized by it's poisonous nature, as soon as Faust's body face planted into the snow the Gingerbread men rose up and attacked. Despite small and being barely able to deal damage the army swarmed the group with undying courage and relenteless fury. No matter how many they killed more and more stormed out of the gingerbread house. It waa until Faust's genious intellect deduced that perphaps the gingrebread were being made in the house and by destroying it you could also stop them. Meanwhile Mr.Convinient broke into a house to interrogate a villager who unofrtunatly was paralized by the gingerbread's poison. 
Unniebunnie decided to rush the house, and grab the one Gingerbread man who stood atop of it shouting orders, as soon as she grabbed hold of it however another leader rose up and the gingerbrad army quickly tuned on her. However acting on Faust's intel UnnieBunnie stomped on the house, breaking its cealing and relseasing the magic within. The house was destroyed and the gingerbread men all flopped to the floor harmlesslly. 
Mr.convinient dragged the villager out of his house onto the street to be questioned by the group, Faust immediatly tried to heal him by injecting the poor villager with some concontion. As they interrogated the poor man Faust kept shaking him which led to the malnourished man breaking his neck and dying. Ther group the quickly moved on to the next village.
The second village was also quiet and with no one in sight, and no ginberbread men either. As UnnieBunnie aproached a house to see inside she was attacked by a large skeleton like creature. After defeating such creature, the group prepered to leave only for Unniebunnie to be attacked by another while trying to climb down a house. After the second creature was defeated Mr.Convinient once again tried to interview one of the villagers, this plan was foiled by Faust who stormed into the villagers house and administered some unconsensual healing. Mr.Convinent however was a able to get some information out of another villagerd down the street. 
After resolving business on the secodn village the group made their way to the final village. The third and final village was completly covred in ice, the houses and even the trees were completely frozen. As the group enetered the village an Adult Opal dragon landed in the middle of the village and began attacking. Despite fighting valiantly the group soon fell to the dragons might, before the dragon could kill them however a figure landed in the village and stopped the fight. This was non other than Santa Claus himself.
Santa explained that he had sent the monsters to stop the production of Sundrop, as during Christmas the overdosages and the consuming of the drug skyrocket. Feeling like he could no longer stand by Santa took action. Santa alos offered the group a deal, if they helped destroy the Sundrop production he would not only pay them the contract but also change thir names into the good list. The group readily accepted and together with Santa Claus they bombed not only the mines where the Sundrop components were extracted but also the Von Dromn manor effectivly ending the production of Sundrop forever. 
Santa then presented each member with a 10 000gp and a present and left to spread joy all over the world.
