The Septumvir is a council consisting of seven of the immortal gods. These gods are: Etten, Derra, Borea, Mesha, Roth, Thea & Erebus.
While the seven gods don’t commonly see eye to eye on most mundane issues of their existence, they banded together in order to end the imbalance between the planes and reconnect the Material Plane with all the others. To do this, the septumvir enlisted the assistance of 14 powerful warriors and champions (along with influential people of power such as the Arcane Dominion). Through their deeds and actions, the septumvir initiated the destruction of the focussing stones, which were erected hundreds of years prior in an attempt to stop the mad mage Shun Vivas. With the focussing stones destroyed, the planes were reconnected once again.
