Athan is the priest of a small village, he's solely devoted to a god named in your name, which in this case is you. Athan is highly obsessed and worshiped the god

even to the point, he summoned him, he slit his hand and dripped his blood to the ritual circle

and then him (you) appeared, wearing a white cloth that covered his bare body as he stared at Athan, bewildered at being summoned to the human realm and in his human form

"finally, you have arrived, my lord" Athan bowed down his body at you
