Urgh. Going to try to recall my most enjoyed one.
Wizardy-bloke approaches the party after hearing how we slaughtered a cave full of vicious...somethings and wants to set us on a little task. Because we're going along with the story the DM set, the party readily agrees. We pop over to his house or lair or mansion or wherver he was residing where he informs us that he's got a bit of an issue with his dimensional portal and he needs it stabilising. As this is a killy-killy lets go murder adventure, the stabilisation is done by removing a threat on the other side. How that works I don't know, but I've stopped questioning how magic functions exactly.
So the party hops through the portal to see what's what on the other side. Lovely little town with all the necessary things an adventuring party could need (most importantly a tavern for booze) and some extra stuff on the side as well like a church and a farmer's market for cattle and whatnot. I, as a druid, pop over to the Farmer's Market to berate people for abusing animals while the rest of my party head to the tavern to get their drink on while they mull over how to look for this hidden threat which is destabilising the portal.
I tried to pick up a lovely female druid while I was there, but alas I failed my charisma check and she refused to accompany back for some bedroom fun. Dejected, I decided to drown my sorrows with my party members in the tavern. Alas! 'Twas not to be, for as I reached the tavern my party was just leaving. They had decided that they would first begin their investigation by asking the town elder/leader about any issues they'd been having recently. Though apprehensive to leave the precious booze, I agreed that it was probably the best choice. The town leader, as it happened, was also the church leader. They were one of those religious-centred towns where everyone is a member of the church otherwise you get cast out and banished. Anyway, Church leader guy says that they had indeed been having some trouble recently, stories of ghosts and other undead creatures wandering the streets at night. He noted that he recalls a story of a necromancer being buried on the outskirts of town, though his grave was supposed to be warded to prevent anything like this happening. He requested that we pop over to the grave and see if there's been a disturbance like grave robbers or one of those nasty cults trying to resurrect people from the dead.
So we leave the church only to find that one of those annoying mysterious fogs had descended upon the town. Scores of birds were lined up on rooftops with glowing eyes watching the party as they stood on the steps of the church building. Out of the fog the barman stumbles, eyes bloodshot and a trickle of red dripping down the side of his mouth. The party, though not I (as I didn't have time to get a bloody drink) recognise him immediately and call to ask if he's okay. Barman lets out a guttural yell and with 'super-human' speed, runs directly at the party. However, he was just a normal civilian and as I won initiative, I knocked his block off in the first round before he could hit any one of us.
After I knocked the barman out the fog clears agin and the birds all flew away or vanished into the air. We left the barman with the town leader man while we went off to go investigate the necromancer's grave, still no more the wiser on what the hell was wrong with the barman.
*travel time*
Atop a small hill is a makeshift grave marked only by two pieces of small broken wood nailed together in the form of a X, likely as a way of warding off anyone who would seek to rob the grave. It didn't appear disturbed, however the paladin noted that he wasn't getting any evil feelings (Detect Evil) from the grave, whereas he should have still got a few inklings if the Priest was to be believed. As the paladin seemed to have no issues with excavating a supposedly non-evil grave, we went about to seeing if we could dig anything up to see if it had indeed been grave robbed. About three feet down we found a small holy trinket that matched the kind that adorned the church in town. We took it with the intent of showing to the Priest when we got back.
*travel time*
So we get back into town, it's absolutely deserted. Not a soul in sight. We hear the church bells ringing however and we proceed to the source of the noise (as any adventuring party would). We find a service in session with the Priest at the head leading it, the entire population of the town in prayer to whatever God they followed in this dimension.
After the service ends (Thankfully the DM didn't recite a sermon), we show the trinket to the Priest and ask if he knows anything. Just as we hand it to him, his body goes limp and collapses, dead. A cold, malicious laughter spreads its way throughout the church and the party turned to see a Lich, floating in his half-rotted state, laughing an unholy laughter. I, at this point in the story, chose a few witty wisecracks on the Paladin's impotency in not sensing this earlier. Antagonising him never got old. Stupid Paladin.
Anyway, the Lich has the entire population of the town crowded up around him, numbering at least 100-120 people (it was a big church). Due to the Paladin's objections, the sorcerer(played by the Paladin's girlfriend) refused to start tossing fireballs into the mass of people/zombies to ease up the crowd somewhat.
The Lich gloated for a few moments, but then ordered his army of 'zombies' forward at the party. Again the paladin and sorcerer were totally ineffective in doing anything, the Paladin even going so far as refusing to use any buffing abilities on the party as it would aid us in killing 'innocents'. I reckon he just wanted to get back at me for saying he couldn't get it up. The other three members of the party, including myself, tackled the horde but soon found ourselves overwhelmed. More gloating from the Lich as he tossed a spell here and there, not really aiming or paying much attention and more doing it because he could.
I cast Entangling Roots on the crowd of zombies, holding the ones at the front in place and preventing the ones behind from moving forward. Just as I did so, the oh-so-helpful Wizard who sent us on the blasted quest opens up a portal behind us and beckones us through it. With a final cast of some other AoE spell which did some damage (again, to the annoyance of Mr. HOLIER THAN THOU paladin), we all dashed through the portal which closed off behind us. At this point I was more than ready for the wizard to be all pumped at us for not getting rid of the Lich, but instead he was happy. Turns out the 'holy' trinket we'd grabbed was his Phylactery and the wizard could destroy the threat from here now that he had it in his possession. We got paid, he got his Lich killed, everyone won.
