While the usage of magic varies greatly depending on the nature of the caster, some principles of magic seem to be universal.

Vestigium Edit

Vestigia is described as an afterimage, and can manifest as feelings, smells, tastes and sounds. Intense vestigia can be created by magic, but all living things seem to create some amount of it.[1][2]

Peter Grant developed the term yap-scale, to measure how strong the vestigia is (referring to how much Toby yaps in its presence).[3]

Spells Edit

Different countries and regions have different traditions and spells.

Black magic Edit

Black magic, according to Nightingales definition, is the use of magic in a way as to cause a breach of the Queen`s Peace.[4]


Signare is the individual signature of individual practitioner's spells.[5]
