Who: Satan, Metatron, and Lucifer When: Roughly 400 BCE Where: Jerusalem What: The times, they are a-changing.
Satan was tired. As he sat on the steps of the Temple and looked out over Jerusalem, he could not even feel pleasure that at least the Temple had been rebuilt and the house of God was no longer a pile of rubble. The Temple had been reconstructed by Persian money and Persian goodwill, a gift from their kindly masters. And while the continuing occupation of Israel had made the humans doubt whether God truly sheltered them and loved them (he was viciously pleased about that. Good, good, let them see that they were nothing but ants to be tossed to the bigger insects whenever He wills it), it did not actually make day to day living any less irritating for Satan. The Canaanite gods were always circling, and it was hard enough to keep them out of the city. Once he added in the encroachment of the Greeks and the Phoenicians (and the Egyptians and the Babylonians and every other spirit that came wandering in out of the desert), it was frankly miraculous that the entire city wasn't making blood sacrifices to Baal or Zeus.
Satan wouldn't have cared, since he had said right from the start that humans were untrustworthy swine, but he did not look forward to being caught in the wave of fire and rage that would doubtlessly obliterate the city entirely. And then he would have to live with the heathens, and that would be even worse. He was in the unenviable position of tempting humans to sin while simultaneously shooing them away from the worship of other gods.
His brooding was interrupted by sharp, painful sensation, like someone had smacked him as hard as they could in the side of his head. Satan whirled around, half-expecting to find one of his angelic brothers scowling down at him. But no, he was alone, and the sensation had not been physical. A mental slap on the face, then. The strange feeling had not abated entirely, and he realized that something was causing it.
Satan slipped into the shadows and re-emerged as a carrion bird. He took to the skies and followed the feeling. It led him to Gehenna, the Valley of the Son of Hinnom. It was a cursed place, full of the bones of sacrificed children and heathen altars, and Satan gave serious thought to just turning tail and flying back to Jerusalem. But he'd come this far, and curiosity drove him onward. He landed in the rocky dirt and transformed back into a human shape.
