Reading the Horus Heresy - Lupercal! Lupercal! Lupercal!

"I was never a Son of Horus. I was and remain a Luna Wolf. A proud son of Cthonia, a loyal servant of the Emperor, beloved by all. I am your enemy."

— Garviel Loken's valediction to his former gene-father Horus Lupercal

"It's not about the Power, it's how you wield it."
-- Horus Lupercal, Warmaster
