Vessel
A finance trader misses the birth of his child because he is in a hotel room with someone else. His decline from there looks like ordinary addiction, and everyone around him treats it that way. It isn’t. A Bacchanalian cult has identified him as the next vessel for their god, and is quietly feeding the spiral. At a black-tie gala he urinates on an ice swan in front of the press, and the internet decides he is an anti-capitalist hero.
Instead of ending his career, it makes him famous. Then the horns come through, and his publicist rebrands them as his USP. His wife pushes through a party to save him, is swallowed by the crowd, and he notices she is gone without asking where. Offered one last chance to walk away into a small mortal life, he chooses godhood - not because he is consumed, but because being human hurts and being divine feels like freedom.
