What are the lyrics for undertaker's ministry theme?

Although it is mainly instrumental, the Words spoken are:

Anail nathrak,

Dorthnei diednei,

Accept the Lord of Darkness as your savior,

Bathnal nathra, de era

Allow the purity of evil to guide you.

Anail nathrak, Dorthnei diednei,

Anail nathrak, de era umbrana
