Here are some concepts I just finished for another of my projects.
I have a medieval setting in which humans have been enslaved by another race, some tall, dark skinned, dreadlocked and aztec-like folks called Ortans.
A bit of story:
Humans live trapped in cities. In order for the adventure to truly start, you have to get out of your city.
And one way to do it is through some very old, dreaded catacombs where the dead sleep.
And the dead are very sensitive to noise..
I did a very thorough research about mummies and the like to see how the dead become.
Next step for them: 3D!
