Is the Invisible God real?
Even if it is real, if mystery predates law and reason, it can't be all-powerful. Infinity rune is owned by Arachne Solara, and it dosen't even have a Mastery rune. The ultimate creator and prime mover of cosmos who can't even master itself, and less infinite than enforcer of the Cosmic Compromsie?
Also, in the numeric order of the Cults, the Invisible God is penultimate, located below the Horned God and followed only by the Lunar Gods. Wondering whether it does intimate that the Invisible God is the lastest god to come, or at least be revealed, in Time. Considering mystery predates and hold precedence over law and reason, perhaps the former might be closer to the truth.
