Since there is a gloomy atmosphere I am playing around with the idea that the player carries a lantern. I mocked up this quick lantern and arm combo to get an idea of how it looks. It definitely blocks too much of the screen. My next mock up will be of a staff with either a glowing jewel or small hanging lantern. 

This also opens up the idea of different colored lamps revealing different symbols or something else. 

Interesting...
