There are rows of long brown wooden seats, a grey stone floor and transparent glass window panes depicting religious iconography.  There are also copies of religious literature available.
Nave, Inside Church
congregant
preacher
I am a preacher who does not believe in the deity. I once did, before I saw how corrupt and decadent my church is. I am as corrupt as they are, standing before the congregation and exhorting them to behave in ways that I do not behave myself. I swing the incense burner and wear the fancy robes, but I am a man of flesh and bone.
Oh, hello there. Good afternoon, reverend.  What brings you to this nave? I am just hear to say a prayer for the week for my departed mother.  Ohh goodness, I'm sorry to hear. Make sure to pray and donate to ensure she has a happy afterlife. I always do, sir.  I am very faithful in my prayers when I can be.  That's what i like to hear, congregant. Go right on ahead. Thank you, so very much.  I will stay out of your way.  No worries, I am not bothered by your presence. Thank you for your generosity, father.  Of course, congregant. What else are you going to be doing today? I will return home and cook deer for my family.
