The Mythryn Gambit
A Renewal is singular division in time periods between Chess Games of the Deities. It marks the beginning of a new game, and the allotment of power to deities by the Mystic. There are thought to be several renewals since the Gods trumped the Primordials in combat, but only a god or a valuable piece would be able to recite how many.
The time allotted for Chess Games varies. Sages even speak of a game that lasted a single year, but whether that claim is valid is unclear. Regardless, the Renewal is the only point that Gods can willingly descend to the world and affect it. Only during the creation phase can Gods directly affect the mortals’ world. Once that phase is over, the Gods ascend to the Astral Sea and play their game, communicating with single or multiple Exarchs who put their will into action.
