RTKD seal center

The seal of the Cook-Ryu family was agreed upon 3//20/2013 and is utilized on all official documents and properties of the Cook family. It is the representation of the four elements (earth, air, fire and water) circling on a pinwheel, encompassed by a thick black circle, which represents the circle or wheel of life, death and continuation. The moon can be seen beneath it rising, representing the rising of night and fearlessness in the face of the unknown/uncertainty.
