I shall be your mentor.
First, and most importantly you must give in.
Give in to your Anger.
Give in to your Dark impulses to lash out at those around you, to punish them and cause them pain.
Give in to your feelings of Hatred... sweet, sweet Hatred... make life a living Hell On Earth for those pitiful mortal creatures who dare befoul your horizons with their insipid weakling mewlings...
Crush them!! Grind the ooze, and gore from the fragments of their skulls between your grasping Fists.
Revel in your Strength, and know this your Fear, and Anger, and Hatred shall make you mighty, and will bring the souls of your many victims to the every hungering maws of the Blood Godz.....
...Go forth! Strike Terror into your Enemies! It is good to have Enemies, for you can sever their heads form their frail sickly necks, and drink their sweet sticky Blood.
Yes, I shall be your Mentor. And you shall be my Apprentice.
Strike from the Shadows with no warning, and be swift to take the Vengeance I can feel burning so brightly with in your chest...
...and cook up some Ribeyes, because they taste awesome.
