I must say I doubt Lovecraft and definitely not I appreciate if this turn out some shounen power fantasy leeching peerage from H.P:s legacy.. Even if Cthulhu is public domain, genre is going to be so.. sooooo wrong.
The man was obsessed with cosmic horrors, fear which cannot be described for it is without permanent shape and too amorphous. Fear which cannot be controlled for it will squeeze in from spaces left between nail and timber. No safe strong enough to hold it, no vault big enough to fit it, no words to describe it, no painting will hold it.
"Become the Lord of Cthulhu".. There should be a limit how much of a precocious piss-ant an unimaginative author who cant release a story without parasiting whales can be.
