Majarrin was the head because:
they look alike, and Majarrin's head was spouting obcenities after it was lopped off. Also, he hates Balor because Connacht (Balor) killed him, while he hates the light because he was the leveller once upon a time. Which explains why he hurt both sides in the war of the fallen lords.
Ok if Tireces is the first hero and the Leveller, and Connacht is the old hero and the Leveller, then you'd think that most of the time, the hero becomes the leveller. Therefore, it is safe to assume Majarrin killed Moagim. Therefore, he is the 2nd hero. Of course, I want to know who Sorgayoth was origionally if Tireces was the first true hero.
btw anyone else think it would be cool to have Myth 5 be where Tireces kills Sorgayoth the Flayed?
