Here is a claim that sounds like it cannot be right. Learn more about a creature and you are more likely to succeed at calling it. Not learn the right formula. Not have more power. Just know more — habitat, habits, what it does, where it turns up. The second of the ten trades is built entirely on that, and the sentence carrying it is unambiguous: the more a Wizard knows about a magical creature the more likely that Wizard is to succeed in conjuring it or using it for a particular magical end.1
Which makes the trade a strange one. A Bestiologist is not a conjurer. They do not call anything. They are the person another wizard goes to when they need to identify or locate a creature — and their reading is somehow load on somebody else's operation.
The role is defined by the request rather than by the ability. A Bestiologist is the one to go to when a Wizard is trying to identify or locate a particular creature of a magical nature, and they know about magical creatures, beasts and creatures of legend better than anyone else. The reason this matters is practical and it is stated plainly. In the magical world a wizard may need to find, contact or employ the services of certain magical creatures in order to better cast an incantation or achieve successful results in a given operation.
Employ the services of. That is the same arrangement running under every conjuration in this curriculum — you are not the one acting, somebody is acting on request. What the Bestiologist supplies is the part that comes before any of that: who to ask for, and where they are.
Three things are held on each creature. Habitats, habits, and a creature's array of magical powers. Where it lives, what it does, what it can do.
The categories are given as a closed list and it is the only creature ranking in the volume.
Elemental. Supernal. Infernal. Woodland. Mythological Creatures. Impossible Creatures. Dimensional. Planetary.
One gets a footnote: Impossible creatures are those which regularly are composed of many others, also known as cryptids. So a griffin — lion and eagle — is Impossible, and the category is defined by composition rather than by rarity. The others go undefined and the sorting logic is not uniform. Elemental, Supernal and Infernal sort by which realm a thing belongs to. Woodland sorts by terrain. Mythological sorts by where the record of it comes from. Dimensional and Planetary sort by scale of location. Impossible sorts by what a body is made of.
⚠ Six ways of sorting in one list of eight. Reported as printed.
Take the operating claim seriously for a moment, because it explains something about this curriculum that otherwise looks like padding. Every conjuration in the working material comes with a portrait attached. The water elemental turns unruly if it is not re-cast daily. The dwarf is greedy and has to be dismissed with courtesy. The fairy cannot be housed because its magic is too great to contain. A hero of Heaven comes only if the fight is just, and the person who called them starts to resemble them.
None of that is procedure. It is character description — and on this trade's stated principle, character description is exactly what makes the call land. Knowing what a thing is like is not background for the conjuration. It is part of the conjuration.
Which is why a Bestiologist is useful without ever casting anything. They hold the half of the operation that lives in the caller's head, and they can hand it over. The mechanism is never explained. Nothing says whether the knowledge changes what the caller does, or what the creature perceives, or whether a being simply responds better to somebody who has taken the trouble. The claim is stated and left.
One line of the entry is unusual for this material because it declines to legislate. A Bestiologist might know a little of all eight categories, or dedicate solely on a particular group. However, each Bestiologist decides what to do; there is no rule or specification to follow.
No rule. In a curriculum that specifies drop counts, hours of the day, numbers of circuits and which hand a stone goes in, this is one of very few places where the practitioner is told the choice is theirs. And it sits directly against the mythology instruction earlier in the syllabus, where attaching to one pantheon is said to close off further lore. Here specialising is fine.
The boundary is drawn explicitly, and it is drawn in a way that leaves the trade oddly placed. Not Conjurers in their own right, the Bestiologist may have a considerable amount of magical knowledge regarding how to conjure these creatures or how to acquire them.
May have. So the knowledge of the calling procedure is optional for the person who knows everything else about the creature. The trade is defined by the catalogue rather than by the operation, and the operation belongs to the next trade along.
What they do supply beyond the catalogue: they know where these creatures can be found in the magical world and how to benefit from their abilities and presence. Location and use. Which, put together with habitat, habits and powers, is a field guide rather than a grimoire.
The reading list is short and every item on it is checkable, which makes it one of the more grounded lists in the volume. Leadbeater's collection of astral and elemental books. Ancient bestiaries like the Aberdeen Bestiary. Medieval creature catalogues. Books on myth and legend. Books on popular folklore. Plus the world's mythologies and religions.
The Aberdeen Bestiary is a real twelfth-century illuminated manuscript held at the University of Aberdeen, and it is the standard example of the medieval form — an animal, a description, and a moral reading attached. C. W. Leadbeater's Theosophical books on the astral plane and nature spirits are also real and are exactly the sort of source a modern practitioner would reach for.
What the list has in common is that none of it is a magical operating manual. Mythology, folklore, bestiaries, catalogues. This is a trade you enter by reading descriptions of animals.
Build a file on every creature you meet, with three fields. Habitat. Habits. Powers. Those are the three the entry names, and they are what another wizard will actually ask you for.
Decide early whether you are a generalist or a specialist, and know that either is permitted. This is one of the few choices in the curriculum left explicitly to the practitioner. Read bestiaries rather than grimoires. The Aberdeen Bestiary, medieval catalogues, world mythologies, folklore, and Leadbeater on the astral and the elementals. Descriptions of beings, not procedures for calling them.
Sort what you learn into the eight boxes. Elemental, Supernal, Infernal, Woodland, Mythological, Impossible, Dimensional, Planetary. The sorting is uneven and it is still the only ranking this material gives you.
And treat the reading as preparation for somebody's operation, including your own. On the stated principle, a creature you know well is a creature more likely to come — so the file you keep is not reference material sitting beside the work. It is part of it.
The eight categories, the operating claim and the reading list are all in the Bestiologist entry of the ten Wizardly Trades. This is the Eldest Tradition warrant on the source stub. 🚩 SINGLE SOURCE for the framework.
The Aberdeen Bestiary and Leadbeater's astral and elemental books are real and obtainable, as are medieval bestiaries generally. ⚠ Cryptid is used in the footnote for creatures composed of several others. In ordinary usage a cryptid is an animal whose existence is unconfirmed — Bigfoot, the Loch Ness Monster — and has nothing to do with composite bodies. The definition given is this material's own.
⚠ Six different sorting principles operate inside one list of eight categories, and no definition is given for seven of them. ⚠ The central claim — that knowing more makes conjuring likelier — is asserted with no mechanism anywhere in the ranges read in this build. Unresolved: nothing states how much knowledge is enough, or whether the effect is on the caller, on the creature, or on the connection between them.
Follow this trade and knowledge is power in the literal sense. What you have read about a creature affects whether it comes, which makes study an operational input rather than preparation for one. Follow the working material and the conjuration formulas do not care. Each is printed as a name plus an effect plus its conditions, and none of them lists prior knowledge of the creature among the conditions. The six things required before speaking are a state of mind, a place, a purpose and a memorised text — not a file on who you are calling.
Both are stated in the same curriculum, and the trade that most depends on this principle is also the one explicitly barred from testing it, since a Bestiologist is not a conjurer.
Zero handshakes on this page. The material is a creature catalogue and one unexplained claim about study affecting a call, and the honest partner — knowing a being's character as part of addressing it — is carried inside this build by the conjuration and invocation pages, where the same principle is shown operating on named beings rather than asserted.
Sharpest implication. The more you know about a creature, the more likely it is to come. Which reframes every personality note attached to a conjuration in this curriculum — the greedy dwarf, the unruly water elemental, the fairy that cannot be contained — as working parts of the operation rather than as colour.
Generative questions.
