A Cykea is a structure made out of harmonically locked Archon particles, created through prolonged influence by Archium atoms.

Cykean structures is the fundamental structure of an Archo-spirit. A consciousness that manifests into a spirit. If a creature of any kind absorbs Archium based molecules, which are then converted into proteins and cellular structures, the brain of that creature will more and more be able to form a persistent Archo-spirit.
