Since I didn't have a real idea of what the interiors would be like...
Inside the tower, I imagined it as a place where a prophet/prophetess lives. Secluded, looking down on the entire temple, proving the prophet's status as a relic from a bygone era.
Baths, and a raised platform where a single mat sits.
The holes in the walls let in light, and help vent the steam from the baths.
Two balconies flank the sides, along with the stairs leading inside.
A small decoration of flowers breed a little life into the stark room, and two chairs sit just out of view in the back, seats for the prophet's attendants.
*Note* this room was built when I did the tower the first time
