Preserving is a lesser known arcane tradition focusing on the use of magic to protect, improve and understand. Preservation wizards seek to prevent magical accidents, limit the unthinking use of magical artifacts by those who cannot comprehend the arcane power they wield, contain wild magic events, and preserve interplanar boundaries. Some Preservation wizards are members of arcane organizations dedicated to systematically training spellcasters capable of policing and preventing the abuse of magic within a realm, others are lone wanderers who have learned their specific skills by simply trying to survive in the aftermath of large scale magical accidents.
Most preservers rigorously stick within the confines of their discipline, studying only abjuration, divination or transmutation, but some seek a deeper understanding of how the weave of arcane magic fits into the web of life and mirrors interplanar connections. Studiously learning about balance and harmony at the feet of learned druids, clerics, rangers and monks leads some preservers of this latter type to multiclass, for how can one preserve what one does not understand?
