Im voting for
Name: Ata'botl, (literal translation: the prophecy/sequence of permanence), the Rippling Womb, the Yet-Made, the Nothing Devourer, Watersnake, the One Who Stands Between,
Representation: rippling water, two separate stones surrounded by intersecting, concentric waves, a blank followed by a dot followed by a circle, a Water Moccasin, a Mauisaurus (it's long neck like a predatory snake emerging from the ocean)
Category: Creation
Variety: Craftslizardship, especially the birthing pools
Domain: the interface layer between Material and Warp, particularly as is used in geomantic process of designs that cause a sequence of changes to ripple back and forth between the two until they cause something to come into being,
Methods of Worship: making a new temple where previously there was nothing, sinuous shifting formation based line dances, percussive music, a recounting of the rippling chain of causation from the birth of a lizard folk to great events caused by that birth, a specific geomantic construction that sets the border of reality thrumming in time with the percussive music. Birthing Pools, a Slaan expounding on the prophecy of the Old Ones
Favored Foes: saboteurs, destroyers, and natural disasters. Those that would break what it has made.
Blessing Thematics: geomancy, enhanced construction quality or speed, enhanced craftslizardship, increased birth rates at the Birthing Pools, added features or phenotypes not in the original design. Bubbles of the twilight state of being halfway between Material and Warp, allowing safer venture deeper into the warp or somewhat limiting the capabilities of a manifest daemon.
It appeals to my love of infrastructure management and construction on an almost primal level
