Yer spirit gits strong wit prayin', boy. If yer spirit ain't strong-like, ya must be doin' somethin' wrong...Spirits live within each living thing, and are the primary source of magical power for most in Umqwam.
What is believed to strengthen one's spirit changes from culture to culture, and religion to religion. One group believes that spirits are bolstered by adamant worship and devout following of their faith's tenets. Another believes that it is strengthened through study, and knowledge. Neither are correct. In truth, spirits gain strength from balance within oneself. Balance of happiness, and sadness. Peace, and chaos. Work, and play. Masculinity, and femininity. One needn't possess every type of balance to begin casting spells— just one. Not all balances are equal, either; often, correcting and maintaining whichever is the most imbalanced within oneself is the key to unlocking their power. This creates a challenge that must be overcome for all aspiring spellslingers, more commonly referred to as saawkamut.
However, changing one's Tsaaw is a mere shortcut to change. It corrupts oneself by rapidly rather than slowly changing who they are. Memories are warped or forgotten, opinions, tastes, and behaviors vary wildly— it is a gamble for a better self, and one that is seldom successful.
Each spirit has a core called a Tsaaw. These hold great power for each person, as they are the center of their being. Should one wish to start anew, begin a new life— they may wish to work from the ground up by changing their Tsaaw and thus their very being. A Tsaaw can be changed through ritual, rare minerals, and forbidden spells.
Changin' yer Tsaaw is like takin' a shotgun t' an unfinish'd basket, rather than simply weavin' it.
