Everything that the Dahaka says is really just the voice actor reversed. What he is really saying is:
• All who have come before you have fallen.
• No one escapes the Dahaka.
• Your end is near.
• You will be removed.
• Disrupt the timeline no further.
• Come to me. Come to your death.
• You are quick, Mortal. Quick to die.
• You can not escape your fate.
• It ends for you the same as all who seek to change their fate.
• A good fight and this outcome was inevitable.
• It was a mistake for you to even try.
• You will never be rid of me.
