Logos is the power that controls all matter and energy in the universe,i.e. "the very fabric of the cosmos" [1].

The Eloh, the benefactor alien race, have superior knowledge of Logos and are able to use it as a psionic power, controlling matter and energy with the power of mind. They share their knowledge with other races in the universe through Logos symbols , which form both a pictographic scripture and allow for understanding the Logos power, and to use the Logos abilities. Knowledge of Logos can be seen as a science, philosophy or even religion.

Note: Contrary to common intuition, the name "Logos" is not the plural of "logo". It does not refer to the symbols used in Eloh scripture. Instead, it is an uncountable noun derived from the ancient greek word λόγος (logos) which in philosophy stands for the fundamental order and principles governing the cosmos.

Logos elements Edit

Typical Logos symbols

Main article: Logos element

Logos elements - also known as Logos symbols - form the pictographic scripture of the Eloh, which they use to communicate with other alien races across the galaxy, and to teach them the power of Logos. Learning Logos symbols allows the player to decipher text messages from the Eloh found in various places across the game. At the same time, learning a particular Logos symbol gives the player insight into a particular aspect of Logos and allows him to utilize any Logos ability linked to it (as far as his class allows).
