The Elders are ambivalent, god-of-the-gods things. They are the only immortal creatures in SHFBT, and are not known/worshipped by regular society. There may be cults surrounding elder worship.
Elder of knowledge.
Elder of strength.
Elder of magic.
Gods in SHFBT are not immortal. They do not age, and have great powers, but are able to be killed. They can be grouped according to several traits, such as their alignment with the other gods; primarily Gods of the Right or GotR, Gods of the Left, or GotL, and Gods of the Middle, GotM. GotR and GotL are often in direct conflict with one another.
God of the sky, father of creation. GotR.
Goddess of the sea, mother of creation. GotR.
God of the beneath. GotR.
God of the mountains and desolate places. GotL.
God of battle, conflict, and war. GotL.
God of the forests and wild creatures. GotL.
Goddess of death and fate. GotM.
Goddess of the harvest and rivers. GotM.
Goddess of chance, luck, chaos, and outcomes. GotM.
Others are gods-that-aren't-gods. They oppose the gods themselves, but seem to have less influence on humanity as a whole. As such, they don't have special descriptors. Like the Elders, they are not known much by regular society. Several others may have cults surrounding them, however.
