1. Cores.
1.1 What is a core?
The core of a wand is its central part. Its heart. Its soul. Once part of a living being, the core together with the proper kind of wood helps the wizard/witch to have a very powerful wand.
Acording to Mr. Ollivander: "Every Ollivander wand has a core of a powerful magical substance. We use unicorn hairs, phoenix tail feathers, and the heartstrings of dragons. No two Ollivander wands are the same, just as no two unicorns, dragons, or phoenixes are the same."
So this leads us to the next statement: Every wand is different from another wand as a fingerprint form one person is different from another's one. And that there can't be power in a wand with no core in it.
Note: Multiple cores will NEVER placed in a wand at the same time!!!
2. Types of cores.
2.1 About cores and other magical menageries.
In our first introduction to him, Mr. Ollivander assured that his wands are produced using cores of only unicorn hairs, phoenix tail feathers or heartstrings of a dragon. He implies that wands cored with other materials could tend to be temperamental, unreliable, or otherwise unsatisfactory. Clearly Mr. Ollivander and his predecessors have limited their wand cores to those three materials, because these have proved to be the most effective and consistent in quality of response. But maybe that just works as these magical animals can be considered common in Britain. But as we now know, there are other core materials used in wands, like the ones in the wands of the Beauxbatons Academy of Magic (veela hair) and probably the Durmstrang Institute students, and leprechaun hair and Hippogriff Talon. And surely the sudents in the magic schools in Brazil and USA and other parts of the world get different wand cores same as different woods too.
2.2 A classification of common and uncommon cores and their magical properties.
Phoenix Tail Feather
We can state that the feathers of a bird have a deeper involvement with the bird than the hair of a beast does with the beast. Why? Because a bird's feathers are not merely its covering, but its tools. Without its feathers, a bird cannot fly. Period.
So the wands cored with Phoenix feathers are cored with anything other than those feathers that are necessary to flight; namely the quills of the wings and the feathers of the tail, which help to stabilize the bird's progress through the air.
Wands with Phoenix feathers are most likely for encounter spells used in magical combat and defense.
Unicorn Tail
The hair of a beast is a superficial attribute. It may be removed with perhaps some discomfort, but no actual harm to the creature.
Unicorns are mythical horse-like creatures with one spiraling horn growing from its forehead. Though the popular image of the unicorn is that of a white horse differing only in the horn, the traditional unicorn has a billy-goat beard, a lion's tail, and cloven hoofs, which distinguish him from a horse, usually seen as a symbol of immortality, grace, purity, love and the magic of working miracles.
Wands with Unicorn Tail hairs are particularly strong at charms.
Dragon Heartstring
Dragons are commonly portrayed as serpentine or reptilian, hatching from eggs and possessing long, typically scaly, bodies; dragons are almost always portrayed as having large eyes, a feature that is the origin for the word for dragon in many cultures, and is often (but not always) portrayed with wings and a fiery breath. Unlike the harvesting of feathers or hair, to collect dragon heartstring requires the death of the dragon. The number of wands which can be cored with a single heartstring probably varies with the breed of dragon and its age or size. And, coming from an internal organ, some form of preservation is probably required before it can be effectively used.
Wand with Dragon Heartstring cores are good for Transfiguration.
Hippogriff Talon
A Hippogriff is a legendary creature, supposedly the offspring of a griffin and a mare.
The reason for its great rarity is that griffins despise horses, which they regard with the same feelings a dog has about a cat. It has been suggested this idea was strong enough in medieval times to produce an expression, "to mate griffins with horses", which meant about the same as the modern expression, "When pigs fly". The hippogriff was therefore a symbol of impossibility and love.
As Hagrid explains, hippogriffs are very calm, powerful giants, but are touchy creatures and demand respect.
As with dragons, the hippogriff must be dead to take the talon for use it as a wand core.
he use of Hippogriff Talon in a wand as a core, results in a wand that demands respect.
Veela Hair
The Vila, or Willi or Veela, are the Slavic versions of nymphs, who have power over storms, which they delight in sending down on lonely travelers. They are known to live in meadows, ponds, oceans, trees, and clouds. They can appear as swans, horses, wolves, or, of course, beautiful women. The Vila may have inspired the Veela, magically captivating women who put men into a trance when singing or dancing and turn into hideous bird-like creatures capable of throwing balls of fire when angered.
The only known wand with a Veela hair belongs to a girl from Beauxbatons Academy of Magic and the hair comes from her grandmother, so it seems that those are not very common as wand cores.
Veela hair produces quite tempermental wands, understandable because of the volatile nature of the veela themseleves.
Leprachaun Hair
In Irish mythology, a leprechaun (Modern Irish: leipreachan) is a type of male elf said to inhabit the island of Ireland. They are a class of "faerie folk" associated in Irish mythology and folklore, as with all faeries, with the Tuatha De Danann and other quasi-historical races said to have inhabited Ireland before the arrival of the Celts. Leprechaun hair as wand core is mostly popular among Irish Wizards.
Other cores used in magic wands are:
-Runespoor Fang
-Chimaera Scale
-Ashwinder Ash
-Demiguise Hair
3. Relation between core, wood and the owner of a wand.
3.1 How wizard, core and wood match to make powerful magic.
Wands are not all cored by the same material as while magic operates across a broad range, each individual wizard is likely to work most effectively when channeling magical energy with the proper core/wood. It is like a resonance, when your magical powers vibe at the same rythm as the core and the wood of your wand.
The core of a wand is modified by the wand's wooden casing also, so it will respond most readily to the wizard whose inherent harmonic range is the best match for its own natural "resonance". The wand "chooses" the wizard largely because while the potential range of any wand is likely to be greater than that of any specific wizard, with a good fit the individual base resonance of wand and wizard will match.
But an experienced wizard should be able to channel magic through a wide variety of wand types. But a proper fit of wand to wizard is essential for young wizards who have yet to master the skill of channeling magical energies through a focusing device, such as a wand. Following this analogy; Charlie's old wand fit Ron reasonably well, since they both needed the same general type of focusing "correction", whereas Neville, with his father's wand, could not see the blackboard.
So in conclusion, the correct wizard with the correct combination of core and wood in a wand will help you to cast spells in the best way possible.
3.2 How to put a core in your wand.
Once the core is selected it must be placed inside the wand. This is the most delicate procedure in Wandcraft, coming after sanding, but before the varnishing of the wand. One method is to drill a hole in the handle, being very careful to not traspass all the wood. It can be done at the rear of the wand, which is the most thick part of it. In the hole you must tuck the core and then you have to seal it. You can use the wood dust from the drilling and glue. This way the core will remain safe in the wand.
