Vident Obscura classifies entity by type and power level. The power level is determined through the physical changes in the surrounding environment measured through a calibrated Athrometer which measures the displacement of energy caused by the entity. The unit of measure for this displacement is called the Oswald symbolized by the cyrillic character Yu (Ю). This measurement measures the displacement of Aether within a region, the official scientific definition is a measure of the aethic displacement requires to alter the local aether field by 1 Aethic-Volt symbolized by the cyrillic Iotated A (Ꙗ). The Oswald is used to measure the presence of a disturbance in the Aether over time.

Aethic-Volt
This unit measures the potential aethic-energy stored within a region. In terms of magical energy it measures the potential energy build-up within a region in the local Aether outside the body. In terms of psionic energy it measures the converse, the potential build-up of energy within the body's Aether. In both cases the energy measured is the potential energy prior to equalization or release toward a particular unit of work. Similar terminology exists of the Aethic-Watt and Aether-Ampere describing the interaction and usage of Aether as a form of energy. Though the relationship between the 3 units is similar to that of their physics counterparts, their related calculations is different.
In most practical cases of measuring the Aether in a region of space, the Aethic-Volt and the Oswald are the two primary units of measure.

The amount of work which can be performed with the displacement measured by the Oswald is exponential and uses the formula:
Origin of the Oswald
The unit of measure is named after Oswald Coldstone a resident of England during the height of the study of the occult in Europe. Coldstone was different in that he actually had some family ties to the study of magic and the supernatural. His grandfather passed on to him an Athrometer, which he spent his life studying both the construction and use of.
Coldstone described the intensity of magic, psionics, and supernatural entities in terms of the disturbance they leave upon the surrounding world, calling this the supracorporeal shadow. He measured this as a positive integer computed from the difference between what he called the supracorporeal and the infracorporeal. Through this he measured the movement of Aether from outside the body to the inside. He further perfected this and discovered a mathematical representation of this using differential mathematics. Having consulted with some of the best minds of a the time, he perfected modifications to the Athrometer allowing it to measure both the direct intensity of the local energy but also calculate the supracorporeal shadow.
