The Fall of the Gods: I Became the Successor to a Seraph

[Behind the scenes, The Fourth Calamity, Western fantasy, not a power fantasy]

A great war raged between the Celestial Realm and the Underworld. The gods of both realms suffered heavy casualties, and the people of the continent of Polar were left to endure unimaginable torment.

The protagonist accidentally transmigrated into the heir of the six-winged seraph, the God of Light and Judgment, and brought along players as The Fourth Calamity, offering this world "salvation."
