I believe the three volumes of the Erebonian Folktales are split into themes. The third and last volume contains lore pertaining to the Great One and the curse (Crimson Demon, Dark dragon, Immortal King, and Great Knight), the second pertains to the Tribes of Earth and Fire, as well as the Holy Beasts (Witches, Gnomes, unicorns and vampires). The first volume refers to lore that the continent of Zemuria shares and pertains to cosmology (animism, fiends/devils and Fairies). I believe fairies have been grouped here on purpose to suggest they are something akin to fiends which are not supposed to exist on the normal plane as opposed to creatures associated with Aidos, the Sept-Terrion and Holy Beasts.
This is what is written about fairies:
“Fairies are inhabitants of another world, separate from both spirits and fiends. Descriptions of them vary amongst different traditions. Some liken them to young winged girls, while others characterize them as small people. A number of believers also portray them as being represented by small animals. One thing they all have in common, however, is that they enjoy pulling pranks on people. “
In Medieval Cosmology, Fairies differ significantly to the Modern Victorian depictions (the small girls with wings), they were defined paradoxically by their inability to be defined, as they didn’t fit within the cosmic system philosophers devised (the world of four earthly elements and the aether around the , the geocentric model of firmaments and spheres etc.) There were some common elements however such as being ‘smaller than men’, extremely long lived, possession of wealth/splendour, immorality and otherworldly power.
These last two points are connected, because just as these other beings are completely separate from human understanding and morals, so they are with the laws of nature humans followed, which meant they could perform all sorts of incomprehensible feats (conjuring/vanishing great armies and places, transformation, reattaching severed heads, forcing humans to follow rules etc.) Interestingly, these fairies were given all sorts of names, including ‘Longaevi (on account of their long life, think longevity) which was coined by none other than Roman Martianus Capella (or M. Capella) which may be our enforcer’s namesake.
Therefore, my evidence for Campanella being a fairy is as follows:
- His Otherworldliness: Campanella could easily be a being from another plane/realm/world. He frequently uses abilities that break physics/laws of nature including defying gravity, conjuring flame from nothing, transformation of himself and others, teleportation and awareness of the 4th
- Immorality: Campanella is jovial all the time, he doesn’t really seem to have much of a sense of ethics, doing things which entertain him over any sense of loyalty or fairness. He discards or endangers lives frivolously and uses major traumatic disasters like the salt pillar to inspire his attacks.
- His Outsiderness. He is used to observe the plans of Ouroboros, and clearly has a great deal of autonomy given to him by the Grandmaster. Perhaps his inhuman nature makes him the perfect impartial observer. ‘The Fool’ does not traditionally fit into the same role as the other 21 Major Arcana, standing apart from them, further supporting this.
- His longevity: While I cannot give evidence he has been around for hundreds of years, it is known from Joshua at the very least that Campanella hasn’t appeared to have aged.
- His appearance: Campanella certainly looks youthful enough to be immortal. He is also certainly much shorter than the average adult, meaning he fits the classical appearance of a fairy PERFECTLY. While they are easier associated with Victorian faeries, one cannot help but notice his hair antennae as well. Although his ears do have a slight taper, they are not fully pointed (a common fairy trope) or I’d have called it a lock here and now.
- His Mischievousness: Campanella loves to play pranks on people, or put them into situations that amuse him. He is ‘The fool’ both in title and arcana. His personal Jaeger corps are ‘the Jesters’ He transforms your party into fruit, holds Joshua and Estelle back on the Glorious not to stop them, but make it ‘more dramatic’ and frequently messes with his own subordinates. His very demeanour shows he takes very little seriously.
Collectively, there is a strong case that Campanella, and not Beryl or Musse is the fairy hiding in Kiseki.
Additional Note: The 3rd Plane in Phantasma is populated by Folk creatures including what appears to be small animal creatures and pixie-like fairies, among fiends like the Varghul which have appeared in the real world. This suggests there is definitely a link between fairies and creatures from other planes. Perhaps these are what Kevin envisions, with Campanella being the real thing?

Circa 110 ore e non so quanti mesi ormai.
È ancora presto per lui mi sa.
È bellissima
