He is from a rold playing game called Exalted and is from a particular book of that series known as Houses of The Bull God. He is one of four great gods of war. In this case, he is the war god of the south.
A very popular god, he has gained power quickly through underhanded deals, betrayel and blackmail. He often breaks the rules by, besides the what was mentioned already, running bets, gambling rings, using the souls of mortals, interacting with mortals, adopting mortals as children and marring mortals.
In the case of marrying mortals, he has, over the course of many centuries, married countless mortal woman and has even, at one time, came to one in mortal form and had a child. That child, a demigod (also against the rules), created a great warrior state.
All by whom he has married (women) and adopted (women and men), are all great warriors, often the best. He often pits his worshippers in all the lands of the south into almost constant war, pretending to favor one over the other. The result is a constant flow of a substance that, in the heavens, is like currency. This results in him being one of, if not the wealthiest god.
In his gambling ring, which he runs openly since he so very easily gets away with it (including inviting the judges and regulators that are supposed to curve such things) involves running mock wars on a large table. It is kind of like the Battlefield, or Command and Conquer video games, only it involves using the very souls of past great warriors and devout worshipers to Ahlat. The souls, when not in play, are locked in and in the form of the many tassels that adorn Ahlat's blood red, skull imprinted cape. The act of using souls in either case is strictly forbidden. Of course Ahlat does it anyhow and gets away with it.
When a god wins big at his gambling ring and mock war games, or does some other great service, pledges infinite fielty and service, etc..., Ahlat awards the god with one of his tassels. Ahlat's tassels are highly sought after, not only for being a great honor, but becuase the soul inside would give perpetual and never ending praise to the new owner. Kind of like a winning lotto ticket where the winner gets a set amount of money for life. Since Ahlat is the only one to have souls in such a form and get away with it, he is the only source of such an item in the heavens.
Oh, and Ahlat is also, in the story of the game, the god of cattle, child birth, fertility, pregnancy, domination, victory, power and vengance. In the case of fertility and pregnancy, he is noted to have the nickname amongst his devout worshippers as "He who makes women heavy with children". The same goes with cattle. In the case of cattle, he is so busy being the southern god of war that he has an underling do the cattle work. Ahlat, being as he is, takes the credit. His underling, also a bull god, but a skinny one with glasses with meek personality, often has a want of being the new god of cattle. He never expresses his desire to Ahlat. LOL. ^\/^.
