Portal to the dead
Rotting corpses sent
Unleashed on the Earth
Gate of Hell brings death
[ Lyrics from: http://www.lyricsfreak.com/m/mortician/intro+gateway+to+beyond_20283027.html ]
Ancient prophecy
Legions of zombies
From beyond the grave
Rotting stench decays

Gruesome, torment
Torture, slow death

Vengeance of the dead
Demon curse of death
