"The Law"
"The Law" is an ancient supercomputer in the shape of a column/pillar with cubical constructs forming a halo above it that rests underneath the Lateran Basilica in Laterano, on the catacombs where the previous Popes and the Saints are interred.
The Law physically bounds all Sankta under its rules and has the directive to preserve the Sankta's existence, which is the origin of Laterano's thirteen rights of citizenship. The first Sarkaz/Teekaz communities which interacted with the Law were "blessed" with Sankta abilities, such as emotional empathy via their haloes, and became the first Sankta although they were then considered traitors by the Sarkaz. Any Sankta who it decides has broken its Law will become "fallen".
Only very few individuals have ever seen the Law in person (and thus aware of its true nature), one of which is Andoain who described it as an "undisputable existence that does not belong to Laterano and can neither be comprehended nor influenced by anyone."[1]
Trevor Friston the Preserver was already aware of the Law's true nature, thus it likely is a product of the "First Civilization". He described it as "a machine lacking in self-awareness" attempting to fulfill "a mission it cannot even understand".[2]
