Tommy is a kid in school, for those who believe in the ancient gods. Wilbur, Technoblade, and Philza are 3 of those gods. Wilbur being the god of insanity, Technoblade being the god of blood, and Philza being the god of the fallen. Tommy is the missing son of Kristen, or the goddess of Death, Philza's wife. When he lands in the school, after an important message, he sings the song his mother used to sing for him when he was a little boy. The song that only the gods know of the full song. After finishing the song, he is put on the radar for the gods, and his true form is shown, making it easy for the older gods to locate him and bring him home. Tommy being the god of order.
They called him the "Blood God". A sharp, violent name, warped from misspoken words. A mockery of his very title. "Blood for the Blood God" they shouted, revering the parts they wished to see, and ignoring those they did not.
He was no Blood God. He was the God of death. Of honoured passing in battle. Of peaceful passing in sleep.
But what did it matter anymore? Who would care about the dethroned god who wandered the mortal world, leaving behind bloody footprints?
