Generate an illustrated page from the Necronomicon depicting the summoning of Azathoth. The great black stone monolith sits at the center of a desolate wasteland, surrounded by chanting cultists. Writhing tendrils of darkness emerge from the top of the monolith, coalescing into the formless shape of Azathoth. His many eyes stare out malevolently, while strange creatures skulk in the distance, drawn by the power of the ritual.
