Tharzidun was imprisoned ages ago by a coalition of deities to prevent the
destruction of existence itself. Although imprisoned, Tharizdun still
has a degree of his original multiverse-threatening power
Special Notes: Divine spellcasters cannot prepare or cast spells unless they are in contact or close proximity to an object or site imbued with some of Tharizdun's power or enabled in some magical way to connect to their deity in some fashion. This is because of Tharizdun's imprisonment by the other deities.
