Me and my friends were playing Dungeons And dragons, the classic, offline, dice, paper, snacks and drinks. This story is not in the original forgotten realms, our Game Master was the creator but used the original game elements.
In this world, the gods were beaten by mortals, so every miracle, divine blessings vanished. Diseases are spreading, people are left alone in this "godforsaken" land. There's only a little few who is not infected with any kind of mutation.
The three of us was investigating in a little village where children were lost and never seen again. The only lead was that only those children whose tooth fell out recently were threatened by this disappearance which was assumed that the culprit was the Tooth Fairy. The straightforward solution to this, which was really obvious was that we had to knock a child's tooth out. So we did, needn't to mention that she wasn't pleased. We waited patiently at the little girl's house, when we noticed that something invisible thing is holding the child, which who can't scream for help, and was taken away. I, as a high elf with good mobility skills, was able to track them into the middle of a forest, then I noticed that the Tooth Fairy is no longer invisible. It was an alien - a xenomorph - with 4 wings[...] I was able to rescue the girl, but couldn't find a clue how to catch this beast. In the tavern, we asked around if anyone could help us, then we got a really convenient help by a elf waitress, who knew what this creature is and how to lure out. She asked for a potion, which ingredient contained poison. We gathered the ingredients, then headed to the place where I found the Tooth Fairy last time. The girl wanted us to drink the potion, so we did. Lucky enough for two of us, we weren't weak enough to be paralised, unlike our third mate, who fell over like a sack of potato. Then we witnessed the waitress turning into the alien-like creature. I had my bow, was able to shoot first, but I couldn't deal enough damage. The next moment was when the Tooth Fairy one-shoted Ayu, my fellow drow elf mate. I fled behind a tree, but it was definietly the end for me since this place was the home ground for the creature. It could have been the end, if Ayu's sword didn't call out my inner mutation.
I turned into a werebear, with sensitive instincts, and was able to track down the Tooth Fairy. I jumped towards her, and slashed hard enough for it to be unable to fight.
