Add a new rule, “Codices”:

The following comes from fragments (believed to be Folio 2) from The Fourth Orthocodex of G. Ray, Master Emeritus in Aeternum:

Each pair of different affinities has its own Face Action; each with a shorthand Symbol:
- Nature/Fire: Radiance (☀)
- Nature/Water: Abundance (♾)
- Water/Fire: Transition (♻)
- Water/Void: Carving (❖) [*, +]
- Fire/Void: Destruction (✖) [*]
- Nature/Void: Opposition (◑) [*]

[+] see Folio 7 for discussion on naming of this Face Action.
[*] see Folio 9 for derivation of the symbology for these Face Actions.

The Fourth Orthocodex may be cited in brief as ‘R4’.
Text from R4 is not considered to be rules that Tesserers obey, unless otherwise specified.
