Im going with the great old ones teaching humans to be like them that is the outsiders.
Outer gods like Yog sothoth have guided beings throughout existence could be tied to
starborns.

“Of such great powers or beings there may be conceivably a survival . . . a survival of a hugely remote period when . . . consciousness was manifested, perhaps, in shapes and forms long since withdrawn before the tide of advancing humanity . . . forms of which poetry and legend alone have caught a flying memory and called them gods, monsters, mythical beings of all sorts and kinds. . . .”
—Algernon Blackwood.
Then, whispered Castro, those first men formed the cult around small idols which the Great Ones shewed them; idols brought in dim aeras from dark stars. That cult would never die till the stars came right again, and the secret priests would take great Cthulhu from His tomb to revive His subjects and resume His rule of earth. The time would be easy to know, for then mankind would have become as the Great Old Ones; free and wild and beyond good and evil, with laws and morals thrown aside and all men shouting and killing and revelling in joy. Then the liberated Old Ones would teach them new ways to shout and kill and revel and enjoy themselves, and all the earth would flame with a holocaust of ecstasy and freedom. Meanwhile the cult, by appropriate rites, must keep alive the memory of those ancient ways and shadow forth the prophecy of their return.
In the elder time chosen men had talked with the entombed Old Ones in dreams, but then something had happened. The great stone city R’lyeh, with its monoliths and sepulchres, had sunk beneath the waves; and the deep waters, full of the one primal mystery through which not even thought can pass, had cut off the spectral intercourse. But memory never died, and high-priests said that the city would rise again when the stars were right. Then came out of the earth the black spirits of earth, mouldy and shadowy, and full of dim rumours picked up in caverns beneath forgotten sea-bottoms. But of them old Castro dared not speak much. He cut himself off hurriedly, and no amount of persuasion or subtlety could elicit more in this direction. The size of the Old Ones, too, he curiously declined to mention. Of the cult, he said that he thought the centre lay amid the pathless deserts of Arabia, where Irem, the City of Pillars, dreams hidden and untouched. It was not allied to the European witch-cult, and was virtually unknown beyond its members. No book had ever really hinted of it, though the deathless Chinamen said that there were double meanings in the Necronomicon of the mad Arab Abdul Alhazred which the initiated might read as they chose, especially the much-discussed couplet:
“That is not dead which can eternal lie,
And with strange aeons even death may die.”
