I have a song about cthulu but im stuck and i need help

This all i have for now

When the stars are right
He will come and he will smite
It will break your very mind
And send shivers down you spine

He will rise up from the sea
And destroy humanity
You may run and you may hide
There is no savior by your side

Pain and suffering,
Is all it will spread
His warning was misread
All you have now is dredd

Death to the world
The Old One brings
Only ancient rites
Will save us this time

His voice bring madness
No human can stand


Any help is got, Thanks
