Natural Laws (Lorica)

Law of Senergy
The Law of Senergy states that: The sum of all energy and entropy in the Asset and Tessa remains constant.

Anchemical (typically called "magical") processes can change the balance between light and dark, by shuffling matter and energy from Asset to Tessa and vice versa, although the atomic identity of that matter is not kept. Any process that transfers energy or matter into the Asset must take the same amount away from the Tessa, and vice versa.

Law of Sentropy
The Law of Sentropy states that: The sum of entropy in the Asset and Tessa is always increasing.

Any physical process not in equilibrium increases entropy (disorder) in the plane in which it occurs. Hence, over time these processes move the universe to a more disorderly state. Anchemical processes may be able to increase or decrease the amount of entropy in either the Asset or Tessa, but only at the cost of increasing entropy in the other plane by a greater amount. This energy gradient is responsible for and necessarily consumed in any magical process, the same way that an energy-entropy gradient is responsible for and necessarily consumed in any chemical or physical process in either one of the two planes.
