Voodoo Magic
This is a school derived from the Loa, the spirit-gods of voodoo, a faith originated and practiced in Haiti. The character is most likely a houngan, or voodoo priest. Voodoo magic is particularly effective in its homeland and in locations of the dead. It has no special vulnerabilities and is considered a "white" magic, but can be perverted into a chaotic magic. This school also uses Sympathetic Magic.
