Dreamspell uses 13 galactic tones that move from Purpose through Presence. That sequence gives structure to both the yearly moon rhythm and the shorter 13-day wavespell arc. When a tone appears inside a kin name, it tells you how the day participates in a larger unfolding pattern.
This is why people often say tones feel like the motion of the cycle rather than the image of the cycle. The seal might tell you the symbolic quality, but the tone tells you how that quality is acting, developing, or completing itself.
