[Verse 1]
Messenger of fear in sight
Dark deception kills the light
Hybrid children watch the sea
Pray for Father, roaming free
[Chorus]
Fearless wretch insanity
He watches lurking beneath the sea
Great old one, forbidden site
He searches, hunter of the shadows is rising
Immortal in madness you dwell
[Verse 2]
Crawling chaos, underground
Cult has summoned, twisted sound
Out from ruins once possesed
Fallen city, living death
[Chorus]
Fearless wretch insanity
He watches lurking beneath the sea
Timeless sleep, has been upset
He awakens
He searches, hunter of the shadows is rising
Immortal in madness you dwell
[Verse 3]
Not dead, which eternal lie
Stranger eons death may die
Drain you of your sanity
Face the thing that should not be
Fearless wretch insanity
He watches lurking beneath the sea
Great old one, forbidden site
He wakens, hunter of the shadows is rising
Immortal in madness you dwell
