Possessor without warning

You know your destiny man,
the seas of blood draw near
behold their phantom fear.
Take my hand and read the oath.
It's canvernous and merciless.
I greet you with a warm hand,
in a state of fear, the last house to be cleared.
Take my hand and read the oath
It's cavenous and merciless.
Take my hand...
Without warning.
