Maoun - also known as the Orange God, the Earth Shaker or the Scorpion Trickster - is a god mentioned in Viktor Welsh's 'Lost Gods' book.
She presents as a monstrous human woman with two horns and nine scorpion tales. She usually is dressed simply in terracotta colour robes and usually carries a mirror with her. Her characterisation in the fragmentary mythology is somewhat confusing as she seems to take on the role of a trickster, home and hearth guardian and in control of the earth at once and none of this is seen as contradictory.
Her most known myths are that of the Debt and the Spider Web.
In the Debt story, Maoun is in debt to one of her sisters (variations differ but usually Murbak). To pay the debt, she disguises herself as a mortal human and works for a royal family of a long-forgotten civilisation. She spent much of her short time on Faerun tricking various dignitaries to part with their money, armies to attack their generals, and worked out a con with the princess (who she had fallen for). The princess would marry into other royal families, Maoun would alter the mind of their betrothed to divorce the princess rather quickly afterwards, taking half of their wealth with them. Eventually, Maoun had enough to pay her debt and was about to bid the princess goodbye when she wanted to not part from her. She then created a mirror so they would always be together in some way as she knew that the princess was in love with someone else and she did not wish to harm her or change her mind.
The Spider Web story is rather more straightforward. A spider builds a web in a house and the old man who lived there notices it and leaves the spider small gifts as he was rather lonely. In return, the spider told many stories to the old man and spun silk to sell. This went on for many years until the old man died. His daughter, a cold and haughty woman who hadn't visited him in years went to view the house as it was worth some money. She sneered at the spider and told her maids to clear the room tomorrow. During the night, the spider prayed to Maoun for protection and touched by the kindness that the spider had for the old man, she offered two protections. She made the spider triple in size and promised that few would harm her or her children. She then ripped the earth from under the house and built a cave, telling the spider to shelter there. The next day when the daughter arrived, Maoun was waiting and stung the woman nine times, killing her. She then told the maid to run and leave the house be. The spider and her brood returned the next day and lived in peace.
