Attack of the Tooth Fairies!

The Cast

Illavir: (Played by Chloe) A female Level 1 Elf exiled to the Human world because she fell in love with the monstrous and extremely powerful Snake-Woman she was supposed to watch over to ensure her captivity. She is looking for a way to go back to her moon to see her beloved again.

Bruce Dragon's Bane: (Played by Cindy) A Level 1 Fighter and adventurer who follows Illavir around for strength in numbers. He has never even seen a dragon before, it's just a name he's given himself.

Rulius and Kelly: (Played by Stephane and Valerie, respectively) A father (Rulius) and son (Kelly) who escaped the clan of thieves and assassins they used to work for (Clan Slahvel) because Rulius overheard the clan was going to use his son as a sacrifice for a ritual. The clan doesn't just let members leave of course, so both are on the run. Both characters are Level 1 Specialists, the 'Lamentations of the Flame Princess' equivalent of the Rogue/Thief class in other versions of the game.


The Story

  It all started on the first session of the new D&D game I'm running. A thief stole the elf's purse, someone else in the party noticed, they caught the thief and stole his purse on top of retrieving the elf's.
  What was in the thief's purse? I grabbed 'Vornheim: The Complete City Kit' and rolled on the "I search the body" Table. I got a 'Crushed fairy/brownie/pixie/leperchaun'... Except I realized it was 'crushed' just now as I checked in the book again for this post. At the moment I rolled it, I totally read 'cursed'!
  So my players open the coin purse and find a fairy inside...

  And I describe it as just a small humanoid and such, trying to keep a mystery around it, but everyone just calls it a fairy and, well, that's what it is. (Not that I confirmed it then!)
  So Kelly decides to keep her. As a side-note, I told them she had her wings cut off.
  Someone in the group mentioned, all amused, that if this was supposed to be a 'Horror D&D' type of game as I had told them, the fairy really wasn't helping the horror mood. But they didn't know it was a CURSED fairy. (That should have been crushed, but I hadn't noticed that and the story turned out to be much more interesting with a cursed one instead!) So I just took the jab and kept silent about it.
  The party went to the village where the adventure hook was, a local couple let them stay in their house for the night, and Kelly treated the fairy akin to a freaking cute hamster pet or something.  
  They just brought this supernatural creature they knew nothing about along with them to the place where they intended to rest.
  Before they all went to bed, I told Kelly's player that the fairy reaches to kiss him on the lips. Kelly does not move, the kiss happens. I had decided that would be how the curse would take effect, so I asked Valerie (Kelly's player) to roll her save against Magic. She failed. We stopped the first session with the group going to sleep and Kelly doing the first guard shift.

  Now this is where things get interesting as I had time to think about how exactly the fairy was cursed in-between sessions. I decided the kiss would be a Fairy Kiss, which acts as a beacon to other fairies of the same kind, as the one they had considered herself a captive of the huge folk without wings.
  When the second session started, I rolled a die to see during whose guard shift it would happen. Kelly's shift ended and she went to wake up Illavir the elf. Illavir had been standing guard for barely one hour when, coming down from the upper floor she saw two swarms of fairies armed with swords heading their way!

  Their wings projected fairy dust all around them. One swarm surrounded Rulius and he breathed their fairy dust. I asked him to roll v.s Poison and he failed the roll, causing him to fall asleep. Illavir took the wingless fairy and held her towards the other fairies, indicating they could have her back. The fairies were having none of that diplomacy crap though! They tried to make Illavir go to sleep too, but as an elf she was immune to such tricks. The other swarm proceeded to part Rulius' lips open and pull out one of his front teeth.
  Players suddenly realized sh*t got real. Illavir made the mistake of trying to cast a Shield spell while surrounded by the swarm, who stung her with countless scalpel-sized blades and interrupted her spell on top of wounding her. Kelly was put to sleep as he tried to drag his dad away. Bruce swung at one swarm with his claymore, but such attacks caught a very small fraction of the swarm.
  The elf fell to the countless stabs of tiny swords. Bruce, left on his own, rushed to the fireplace and checked to see if there was a log he could grab with his hands. I rolled. There wasn't, all logs were covered with flames. Bruce stuck the tip of his claymore in one of the flaming logs and swung it at a swarm. He failed his attack and after a roll from me to see if it would, the log did indeed fly off the tip of the sword and hit a corner of the house. Another roll indicated that, thankfully, the fire wasn't catching on anything surrounding it.
  The fairies used their dust on Bruce, and he too fell asleep after failing his Poison save... I roll to see if the flaming log will burn the floor given enough time and it doesn't. The characters won't burn alive while they're sleeping. Yay.
  So during their sleep... They had all of their teeth pulled out.

  So my players had to talk as if they had no teeth left for the rest of the session. Kelly remained silent and wrote everything he had to say instead, but it wasn't a cop-out as Val actually did write everything and didn't just go "I write...".
  I told them that dentures do exist in this setting, and maybe they could eventually find a Cleric able to regrow them.
  They got no XP from treasure or defeating monsters, but I decided that having them talk like that for such a long time (and still for one more session to come at the very least, very possibly more!) deserved a little something. I checked the guidelines for role-playing XP rewards in the 'Castles & Crusades Player's Handbook' and gave them all 25 XP for their troubles. But I like to think that they learned something about bringing with them a supernatural being they know nothing about.

Tooth Fairy Swarm

Tooth Fairies are obsessed with collecting teeth from their victims and once they have them all, they are content enough to leave without further harming their target. This is generally speaking. If a creature gave them enough of a reason, they might choose to kill their opponent before or after collecting the teeth.

HD: 2
AC: 14
Movement: Flying, twice normal human speed. Walking, 1/4 normal human speed.
Attacks: Sword Stings (1d4), Fairy Dust
Special: Fairy Kiss, Cutting/Impaling Resistance, Tooth Removal

Sword Stings:  As a swarm, they automatically hit an opponent they are surrounding, once per turn. When most fairies of the swarm are armed with swords appropriate for their size, they do 1d4 damage. This represents countless small stings. If they are unarmed, they are unable to cause any damage to a normal-sized humanoid with their bare hands.

Fairy Dust: Once per turn, the fairies can choose not to attack and concentrate on flapping their wings faster so they'll project enough fairy dust from their wings to put their target asleep. The target must be surrounded by the swarm and can save against Poison to avoid this attack completely. Anyone immune or with resistances to the Sleep spell also benefits from the same advantages against Fairy Dust.

Fairy Kiss: If a Tooth Fairy kisses someone on the lips, they must Save v.s Magic. If they fail, 1d4 swarms of Tooth Fairies will know exactly where to find the Kissed. They will arrive in 1d20 hours.

Cutting/Impaling Resistance: Cutting and impaling attacks do half their damage (rounded down) against a Tooth Fairy Swarm.

Tooth Removal: A swarm of Tooth Fairies can remove a tooth from a helpless opponent if they do nothing else that round. If they remove enough teeth, (DM's call) deal 1 hp of damage to the victim.
