Founding
In the second half of the reign of Radiant Ozen I, political power began to be reorganized into two separate branches: the Church of Light and the newly formed Council of Umbar (which would in later centuries reorganize itself as well, creating the Council of Syndicates to deal with technical matters deemed "trivial" by the consuls).
The Council of Umbar became responsible for technical, day-to-day matters, such as maintaining the fledgling city's defenses; managing the newly created city guard, dubbed the "Copper Guard"; as well as trade and political relations with other settlements that had begun to spring up in the fertile flood plains of Greater Umbar and amongst the natural harbors within Varilean Bay.
Regardless, the Church of Light would remain the more powerful of the two, with its Pythia having veto power over nearly all of the Council's policy decisions, with the Pythia's veto only able to be overridden by the Radiant's own veto--an incredibly rare occurance.
