None of it is invented
The rites are the five elements as the old cosmologies actually ordered them — earth, water, fire, air, and ether. The runes are the ten emanations of the Kabbalistic Tree of Life, and they keep their own names: Crown, Understanding, Wisdom, Strength, Mercy, Beauty, Splendour, Victory, Foundation, Kingdom.
These are living traditions, not set dressing scraped for a fantasy skin. They are used here under the names their practitioners use, in the order their practitioners place them, because a system that has been refined for centuries is more interesting than one invented in an afternoon — and because the structure already does what a progression tree needs to do.
Choose an affinity and the tree opens differently. What you attune to is what you become able to learn.
