King Salumon

A king, called Salumon, in a far of land up north gets a visit from a stranger called Ashmedai, who tells Salumon that he shall commit sin and be dragged down to hell, to which Salumon replies with locking himself into his castle and stops leaving his quarters for matters that can be resolved within his quarters. One day one of his maids delivered food to the Salumon, who thought the maid was beautiful and fell in love, despite being married to the queen. One day the maid came in again and the king, unable to contain himself, had her stay the night. The following morning when Salumon woke up the maid was gone, and in front of him stood the stranger, who transformed in front of king Salumon into a blue-skinned three-headed - one head smiling, one head frowning and one head crying - figure with yellow and black eyes and orange teeth. The king recognized the devil Asmodeus, who told Salumon that he had committed the sin of lust and will be dragged down to hell, and so Asmodeus drags Salumon to the fifth hell, lust.

As far as Fyelbelle was concerned: None, really. But people have committed sin, haven't they? As far as Duarvia was concerned: There was a a king named Salumon, wasn't there? And He died, didn't he?   Exactly.

The myth did at some point spread from Fyelbelle to Duarvia, where it is commonly accepted that the myth took place as the far of land is described to be up north and Ashmedai is described to be twice as tall as the local population.

2:1:1 There was once a king named Salumon. Salumon was king in a distant land in the north.   2:1:2 One day Salumon was visited by a stranger, who introduced himself as Ashmedai. The stranger looked different. He was almost twice as tall as ordinary people, and he had a completely different dialect from the locals when he said to Salumon   2:1:3 "You will commit sin and be dragged down to Hell."

This is the first myth to describe Asmodeus' appearance, which greatly influenced how he appeared in later artworks.
