Deep inside the Holy Temple itself, in the most inner sanctum a lone lizard clad with nothing but scales that glimmer an unusual magenta in the candlelight can be seen studying a sacred scroll covered with an ancient, holy script of the lizard people. Supported by a simple, unadorned staff, this lizard can be heard murmuring softly to himself as he scans the sacred scroll with keen eyes, comparing them now and then to other scrolls with similiar writing.
"Tlatloc, the evening prayers are starting!", cries a young lizard voice. Startled from his thoughts Tlatloc answers faithfully, "Alright, alright. Coming!". With a reptilian sigh, Tlatloc lays down the sacred scrolls he had been comparing on the pedestal, and turns to exit this holy inner sanctum. As he turns, a brief glimpse of the writing can be caught, and the writing shines clearly with a bluestone light:

Perhaps this mysterious writing is behind the conch call? The sound of reverent chanting drifts out of the Holy Temple from the prayer hall as the evening prayers begin in earnest taking the last echoes of the conch shell away with it.
