I am interested in this. I am not final on my concept and I will need to do some research for it, but here is my idea:

A god-king with a kingdom styled after Ancient Egypt, with all the religious and other trappings that entails. Someone who has ascended to the eternal throne of a civilisation of monument builders, a true, peaceful and just king who has brought prosperity to his people. However, this has not always been this way. For long, long ago, he was worse than a beggar. A nameless nobody who begged on the streets for money. He knew only that his world was unjust, for he could barely eat and drink enough, along with many others. Indeed, the world was a terrible place before he started to act.

He then received a vision and started preaching religion. He fought against the existing state, he convinced people about his righteous ways, he carved it all out for himself. He made sacrifices for his goal and expected sacrifices to be made in turn. Over the course of many years, his entire world was overturned by his work. And now, having finished it all, having finally delivered the change he sought out in society... some asshole yanks him away and goes "nuh-uh."

He is a little pissed about the situation.
