Must not have been paying too much attention to the quest...there was a long gap between fighting Khazard and the ritual. Hazeel's the only Mahjarrat who might not be there, but to be honest I think portals easily explains that away. There's no reason Zamorak wouldn't just bring him there for players who stopped Hazeel's awakening. Runescape doesn't need a hero...it needs a villain. An all encompassing force of evil that will remain ever-threatening and use chaos to make the peoples of Gielinor tolerate each other, grow strong together, and fight side by side against this evil. I am that villain.
