Exigence

When a lesser god finds themselves in direst need, they may pray to the Unconquered Sun to be allowed to create an Exalt of their own. If the need is great enough, if there is no other way to deal with the situation, and if the Unconquered Sun deems it worthy, then the god will be granted a portion of the Exigence, the divine flame, so they may choose a champion.
The Exigence does not come without cost. Creating an Exigent requires a god to permanently sacrifice a good part of their power, and in the case of weaker gods it may consume them outright. Nevertheless, some gods deem it worth the price.
