What are the gods?
The gods are essentially just stones with faces on them that have different colored eyes and different colored stone. Each one is different, from the red "Hateful God" at the volcano and the blue "Miserable God" under the Snowy Sky Island.
Hateful God (Red) Volcano
Miserable God (Blue) Under the Ice Sky Island
Old God (Gray) Under the Ancient Tree Island
Wealthy God (Yellow) Very deep underground
Lonely God (Transparent) On Petrified Tree Island
What they drop:
Hateful God: 12 Raw Adurite and 11 Essence
Miserable God: 12 Bluefruit, 11 Essence, and 3 crystal chunks
Old God: 32 Essence
Wealthy god: 12 Raw Gold 11 Essence
Lonely God: Literally just Raw Meat and Bloodfruit, and not that many of it either.
