This is a seal invoked for protection against all manner of earthly perils, and likewise, it is invoked for defence during times of vulnerability. The other powers in this seal are related to the names of the rulers of the elements, written inside the cross: Seraf, Kerub, Ariel and Tharsis; these spirits have intimate knowledge of the elemental forces and forces of nature, and how these forces may be manifest under the influence of mercy.
