What is Natura? and how does it differ from Gnosis?

Natura is the difference between your Gnosis score and your race's natural Gnosis score.

Natura is the same as Gnosis, but its the level of Gnosis possessed by an entire species. It applies only to Natural (physical) creatures, and represents the average starting value of Gnosis, although an individual character from that species could have more Gnosis than that.

You can look at Natura and see clearly how Ebudan and Duk'zarist (for example) will have more Gnosis on average than humans.

Thank you. I am trying to translate the sub-paths in arcana exxet and the natura bit was confusing me.

Gaya beyond the dreams, p. 295
