In the Cthulhu Mythos, when would Cthulhu rise?

"When the stars were right, They could plunge from world to world through the sky; but when the stars were wrong, They could not live. "

H.P. Lovecraft, "The Call of Cthulhu"

I believe when the stars are right. He's waiting for some particular alignment which will give him the power to break his bonds and rise from R'leyh.

Hmm...considering how many questions I answer every day on 2012...could it be that THAT alignment is the one? It hasn't happened for 26,000 years...that could be when he was put into R'leyh in the first place. The Sun at dawn on the Winter solstice is going to come up through the birth canal area of the Milky Way and be reborn...why not have the big C rise up and overcome the earth on that day too?!

YES! I have the secret!

Well, those damn Whatleys just won't leave well enough alone, will they? We nailed Wilbur to the old shrine at the crossroads, but did that stop his nocturnal visitations to the hollow hill behind his dilapidated and wierdly luminescent farm? It did not. Strangely, I find that the spirit of Cthulhu has driven me back to the auld practices that I and Professor Blakely had foresaken after the Unfortunate Incident which wrought such inscrutable fame upon dear old Ivied Miskatonic. The hunger gnaws like juvenile rats upon my soul (if indeed I still have a soul).

Walking beneath the tattered and sadly dripping branches of the willows, I thought I heard the first rumblings of the Elder Ones stirring in the dark, damp earth.

Aiee, he comes! He comes. It cannot stay .......

;)

ech-pi-el was kind of vague on this...he just said it would be "when the stars are right,"whatever that means. "That is not dead which can eternal lie,

And with strange aeons even death may die."

Ia!Ia! Cthulhu FHTAGN!!

*nerd mode on*

And I should point out, that as great as Cthulhu is, he is not, REPEAT, NOT, an Elder God. He is a Great Old One. Old Ones need people to keep up with the cult thang to maintain their power. The elder gods could care less about humans--they're pretty ambivalent.

*nerd mode off*

Only the book of the dead knows for sure.

I have attempted to trance for it. But so far, every attempt has failed.

I suppose when all humans worship him. I love the shadow over innsmith.

It's possible for sure

Whenever he wants to. He is an Elder God.
