Jordain vizier

Jordain Viziers were specially trained members of House Jordain who dedicated their lives in service of the upper-class Halruaan spellcasters. They forewent the use of any magic or any magical devices for a broader knowledge of the arcane and a life of service to Halruaa's magocracy.

Culture
Viziers underwent exhaustive training and went through distinct ordeals for their service. This began with an education and dedication to the study and understanding of magic. An upbringing in House Jordain included many academic disciplines, familiarity with legends and lore from a number of lands knowledge of at least 4 languages (including common and Halruaan) and worship of either Azuth or Mystra.

They were indoctrinated to always obey Halruaan authorities and wizards, follow all laws of Halruaa and never cast any spells or use items. Viziers were also expected to maintain abstinence from any spellcasting or use of devices that would mimic or mirror spell-like effects. Failure to do use would warrant the intervention of a magehound

Upon graduation, Jordain viziers are sterilized and are unable to have children. They are also trained to seldom handle money so as to lessen any possible lure and seduction of material goods. These practices exemplify the actions needed to imbue the viziers with their calm, placid demeanor. They were taught to value philosophy over materialism and maintain a demeanor that was unexcitable in the face of wondrous magic.

Abilities
Jordain viziers were masters in mnemonic skills and deductive reasoning; this led to exceptional eidetic memory, as well as drawing exceptionally accurate conclusions. Their honed memories and rigorous and logical thought processes allowed them to make lightning-fast deductions and state reasonable facts about people and places about which they possessed very limited knowledge. This granted them exceptional combat insight

Although they were forbidden from practicing magic, viziers were trained to turn their inherent magic resistance outward into spell-like abilities. They could uniquely counter opposing arcane spellcasters' magic as if casting the spell.
