Age of Aventus
Avernus rules over Death and the Underworld, but these aren’t his only domains. Because of his own origins, fate, and doom. And because he is lord of the Underworld, where gold is common and valueless, he is also the god of wealth.
Although it might seem as though Avernus is connected to Nyx more closely than the other gods, this isn’t the case. Avernus’s realm lacks both the sun and the night.
Avernus wields Mastix, a black spear with an impossibly long reach, like a thin shadow that stretches on forever. The he uses the spear a means of inflicting pain only when he must, but its more frequent function is as a snare to pull the reluctant dead into—or back into—his realm.
Avernus is an effective warden and lord of the Underworld realm. He is not without compassion, but his compassion is limited to feeling on behalf of others what he himself feels, and his acceptance of his fate means that his lieges, the dead, must accept theirs. He idly envies the sunlit world of the living, but only in a daydream-like way. He knows that all mortal souls will eventually join him, which affords him a kind of satisfaction and certainty. When others suffer, it brings Avernus peace, but not glee, because the alienation and banishment of others enables them to identify with his own.
The god of the underworld is worshiped by three distinct sets of mortal beings: those who exalt death, those who desire wealth, and those who pray for acceptance of their fates. The first group is the smallest but most dangerous; they seek to bring about a confrontation between Heliod and his shadow. The second group is largest. Because the dead leave their earthly wealth behind, Avernus has become associated with that wealth, as well as with the abundance of (to him, pretty but valueless) gold in his realm. The final group is closest to Avernus’s heart—those who have been cast out and who seek peace with their fate.
To members of the cult of Avernus, gold-infused tattoos symbolize the inevitable grasp of the god of death.
Priests of Avernus give an occasional reminder to mortals who have forgotten their mortality. Avernus’s minions hunt the Returned and warn those who consider the same folly.
