Well, if the reports are true, then R’lyeh has risen.
And if you think about it, Cthulhu is a clever devourer of souls. The Law of Universal Starbucks Proliferation states that any exposed land mass will have a Starbucks upon it–in fact, as many as the land will support. Therefore, humans must arrive on R’lyeh shortly to commence building of said Starbucks locations. Then, Cthulhu will eat them. Then…the Law persists, so more humans will arrive. And the cycle will continue.
Cthulhu didn’t get to be as old as he is by accident, folks. Make peace with your gods.
