Memoria

A Memoria (Latina: memory) was a magical recording that came in many forms. It was standardly used to preserve a biographic image of the ancestors or accounts of certain events.

Creation and types
Memoriae had no specific form: They could be small, portable objects (preferably goshenite crystals or crystal orbs), or entire buildings (such as the Timekeeper's Palace). What they had in common was their creation, which was a special form of enchantment that embedded the object with magic, creating the recording. In the case of biographs, they were created by saving a complete "ghost" copy of a person's mana signature, memories and personality.

The most common types of memoriae were:
 * Biograph – As mentioned before, a complete recording of the person creating it, usually self-updating as long as it remained in their possession; it does not need to be kept on person for this. In general, goshenite orbs were preferred, but other variants of beryl were also popular.
 * Annotatio – Unlike the Biograph, which recorded a person, an Annotation recorded an event or the memory of a place, and thus were often enchanted upon engraved records of an event.
 * Corpus Delicti – A special type of Annotation used in investigation, especially criminal, recording the past of a place. It was especially useful in cases with few physical evidence and a lot of contradictory witness statements, or in tracing back failure of machines and security systems. The most famous Corpus Delicti of the 20th century was the recording of the Skyjacking of Danzig 1978.
