Basic Information
A wizard's apprentice is a person who is serving an apprenticeship to a wizard.
This will generally imply that they are not attending a wizarding school unless the title is an honorific for someone attending such.
The apprenticeship may be arranged under the auspices of a formal guild or may be a less regulated one-to-one arrangement. Depending on the character of the master wizard the apprentice may be bonded labour, an experimental animal or an actual protegee - a guild is likely to abate the worst excesses to be found in freeform apprenticeships but may not entirely remove them.
