Tooth Fairy (Paths Beyond)
I hate thinking about my own teeth for a variety of reasons, but there is something about teeth as a motif that I find hypnotic. This makes tooth fairies horribly iconic. Paizo took something whimsical from our childhoods, combined it with something awful from our adult years (aka oral hygiene), to make a monster no one forgets. They are brilliant.
What sets tooth fairies apart from other fey is their origin. These greedy nasties typically hail from the Universe rather than the First World, though they are still strongly connected to the latter. Not the have to come from the Universe, mind you, all they need is mortal children living somewhere connected to the First World. The presence of tooth fairies in extraplanar hubs, with their higher mortal populaces, implies the presence of First World energies somewhere nearby - a useful little bit of environmental storytelling. Of course, a sufficiently powerful druid or witch could manufacture these energies as well, either stealing teeth or children to spawn their horrendous little minions. Just be careful with your group’s lines and veils if you go the latter route.
Of course, the other other question to consider is why tooth faeries need all those teeth. Sure, they are sadistic bastards, they use them as decorations, and some need them to transform into monarchs, but are there other reasons for tooth faeries to hoard teeth? What would happen if one of them started crunching them down like candy? Are their fairies out there who cause teeth to decay and abscess within their owner's mouths? What rituals do tooth fairies need the teeth for and why do some of them bargain for teeth instead of steal? Don't be afraid to get weird here, its fine to say the fey compelled to steal teeth, but providing an evocative and twisted rationale will make it all the more memorable.
Tooth fairies are a constant nuisance in Shadow Absalom thanks to the infamous Tooth Gardens. Within this moldering tenement building, canines and molars spread like hideous coral reefs, eventually cracking open and disgorging the sadistic fey gestating within. This phenomenon's origins are hotly debated, it is obvious that this land is touched by the First World, but how and why remain occulted. The two most common theories are that an archfey was buried in this location during a forgotten age or that this was where Count Ranalc's exile began. Either way, this is a place best avoided by mortals, as the tooth fairies are more than happy to act as cat's paws for velstracs as long as they get to keep the victim's teeth.
Faerie rings blend easily into natural environments, unless they come from tooth faeries. A ring of mushrooms is not worthy, but they occur often enough to not raise suspicions and not all of them link to the First World. On the other hand, a ring of teeth growing on the ends of tiny stalks is immediately alarming. Tooth faeries tend these spots carefully, and can open the door between worlds in exchange for an offering of teeth.
The Riftwardens are alarmed when uneven rents begin appearing between the Universe and the First World. The source of these rifts is Mallus the Rotten, a tooth fairy sorcerer with a maw full of miniature wrackworm incisors. These allow Mallus to crack and chew his way through planar boundaries, infecting wherever he passes through with metaphysical cavities. Once these fester, Mallus' rifts connect to the Dead Vault as well, threatening fey and mortal alike with Rovagug's foul influence.
