Local, Eh?
I could go with local. Besides, D&D is plenty site-based (typically). So far, though, I'm still thinking a half-demon fighter/sorcerer, son of one of Orcus' chief minions. Maybe he even carries a cheap replica of the wand of Orcus.
So, maybe the heroes are all travelling into a small town in the foothills of whatever mountain range, and there is a small fortress within spitting distance of town, but no one likes to go there because it is dangerous, and perhaps haunted.
First, Alhandra and Mialee (group A) arrive in town, and they want to go and check out the ruins because Alhandra senses a great darkness hanging over the town. When Tordek, Gimble and Krusk (group B), a middle-aged gentleman approaches them and convinces them to go and search the ruins. The gentleman is actually the older brother of the half-demon, and is hoping that group B will rid the fortress of the fiends and undead so that he can claim a secret of treasure hidden within its bowels. Of course, he doesn't tell them that.
So, group A arrives at the ruins first, several hours before group B. They get close undetected with the aid of Mialee's magic, but when they spot a pair of demons that have cornered one of the townspeople who foolishly approached the ruins, Alhandra attacks. She slices, she dices, but despite her success, she alerts another nearby sentry and soon the three of them are fighting for their lives. In an ambush, the townsperson is cut down, and Alhandra is severely wounded, but Mialee manages to kill it with her arcane firepower.
Now, cut a few hours ahead, and group B enters the ruins and encounters a bedraggled Mialee fighting off another fiendish foe. Krusk charges into the fray and kills it, and Eberk uses his healing powers to revive Alhandra.
After this, the group decides to look for a better way in than through the front doors, and between Gimble and Eberk they manage to find a nearby passageway that leads into the bowels of the fortress. Down here, they encounter skeletons, zombies, ghouls, etc, some of which Tordek vapourizes with his powers, some which keep on coming after he tries. After a mini-boss fight with a pair of necromancers, they make their way back into the portion of the fortress patrolled by demons.
Gradually, they fight and sneak to the lair of the cambion, and there they fight him and whatever appropriately sized pet would fit here, in a big climactic fight. Gimble lulls the creature into dormancy with his magic, while Alhandra and Krusk rush off to fight the cambion. Eberk and Mialee, in the mean time, have their hands full with some minions. In the ensuing melee, the two warriors are doing OK against their fiendish foe, but he manages to sunder Krusk's weapon. The creature breaks out of Gimbles magical hold, and scoops up the gnome in its jaws. Before it bites down though, Krusk sees what is happening and leaps on the creatures back, grappling it, and Gimble is thrown free, but he is bleeding and unconscious. Minor minions defeated, Eberk rushes to heal his companion, while Mialee is left to bring the beast down with her spells, while Krusk is doing his best to keep it away from his companions. Meanwhile though, Alhandra is left fighting the cambion, who clearly has the upperhand. Suddenly, Alhandras weapon is knocked from her grasp, and then the cambion sinks his weapon deep into the paladins side. She turns ashen, and sinks to the ground, grasping the cambions blade jutting out of her. The party tries to come to her aid, but the half-demon erects some kind of flaming barrier around them, but when the half-demon tries to pull out his blade to strike the final blow. Alhandras eyes light up with a holy light and holds on for all shes worth. Forgetting his weapon, he rushes to grab Alhandra's blade, but when he touches it he is burned horribly, for it is surrounded by the same light in Alhandras eyes. Then, in a twist from how the villain rises up silently behind the unsuspecting victim, Alhandra rises up behind the howling cambion, his weapon clenched in her hands, and she strikes him down.
After that, it takes a moment for the fiery barrier to die down, and by the time a weary and drained Eberk can get to her side, her spirit is gone, not that he would of been able to save her, for the last of his powers have already been spent. It takes a moment for all of this to really sink in, and Mialee gets a more than a little upset, because she had travelled for several years with the courageous paladin, on many adventures. After some words, they get back to work and descend down a secret passageway that the half-demon had opened up before they arrived. They find a vault filled with weapons, armour and treasure. One display case though, is conspicuously empty, and then a magic mouth activates, telling the party that they have done a great service to the town, but that he (the brother) has made off with the prize. At this, everyone is quite angry, but the ever curious Gimble finds a hidden compartment in the case holding one last treasure, a magical journal of some kind containing a map and several writings that Mialee recognizes as spells. It appears that all has not been lost, and the scene closes zooming in on a location marked on the map.
In the end, the party heads back to town with the bodies of Alhandra and the person who was killed earlier. They elders promise that a fitting mausoleum will be built for the paladin, and wishes the remaining party members good luck on tracking down the place marked on their map. One of the elders tells the party that he has known the brother for many years, and doubts that he will purposefully attempt to harm anyone, but that he is filled with a great ambition and sometimes makes foolish decisions. The party is wished well in their journeys, and they set out for the location marked on the map.
The End.
Rough I know. Could use -lots- of improvement, but as the quote goes (whether it is originally from Alpha Centauri, I do not know), " With rough tools, we make better tools, and with better tools, we make more precise tools. "
