as fun as that would be it goes against playing as the big bad evil guy in the story.

even if youre a big evil bad guy, you wouldnt walk out of a cave and try to kill everyone right away you'd probably try to figure out some things trade or manipulate people to get what you want and help you so you dont walk out like a peasant trying to kill someone and just die because you start out weak

I believe in the canon of the game there is something "wrong" seeming about you that immediately makes it obvious to most if not all that you are possessed.

Imagine Samara from The Ring trying to casually buy some supplies at the farmers market

Last year when we had a Kickstarter and we didn't have gods and victory conditions in the game yet, we had a couple of stretch goals that I hoped we would be able to add before release - Procedural World, Factions, Servants, Building, a more elaborate progression system. Unfortunately, the Kickstarter failed completely and we had to find a way to even finish the game at all. Right now, since the story is complete, it's no longer an option to rework some of these things (but some like Building may still come) and they will come in a sequel.
