Phoenix
This is the rarest core type. Phoenix feathers are capable of the greatest range of magic, though they may take longer than either unicorn or dragon cores to reveal this. They show the most initiative, sometimes acting of their own accord, a quality that many witches and wizards dislike.
Phoenix feather wands are always the pickiest when it comes to potential owners, for the creature from which they are taken is one of the most independent and detached in the world. These wands are the hardest to tame and to personalise, and their allegiance is usually hard won.
English Oak
A wand for good times and bad, this is a friend as loyal as the wizard who deserves it. Wands of English oak demand partners of strength, courage and fidelity. Less well-known is the propensity for owners of English oak wands to have powerful intuition, and, often, an affinity with the magic of the natural world, with the creatures and plants that are necessary to wizardkind for both magic and pleasure. The oak tree is called King of the Forest from the winter solstice up until the summer solstice, and its wood should only be collected during that time (holly becomes King as the days begin to shorten again, and so holly should only be gathered as the year wanes. This divide is believed to be the origin of the old superstition, “when his wand’s oak and hers is holly, then to marry would be folly,” a superstition that I have found baseless). It is said that Merlin’s wand was of English oak (though his grave has never been found, so this cannot be proven).
