Damascus Steel = A mysterious metal alloy whose exact origin and makeup is still a mystery even in modern times. Damascus Steel holds several unique properties and is often used to great effect against Supernaturals. The Senior Members of the Order of Conquistadors are believed to retain knowledge of how to make Damascus Steel. 
Doxology of Irenaeus = This ancient manuscript from the Church Father Irenaeus would grant insight into some of the oldest mysteries of the early Church (who were the Novatians, was Peter held equal to or above other bishops, etc.).
Dutchman's Mine = The Lost Dutchman's Mine is a famous American legend of the Old West because it characterizes so much of the mentality of that era in time. Supposedly the mine still exists and is rumored to hold enough gold to make any man (any Conquistador) one of the wealthiest people in the world. For more info see this Link here.
