>The plate armour covering Magnus’ daemonic body is embellished
with Tzeentchian runes, their profane symbology creating a
tapestry of madness. A great horned crown adorns the Crimson
King’s head, through which he exudes an aura of protective energy
around himself, shielding his physical and mental essence. The
futility of defying Magnus’ wrath becomes clear when enemy fire dissipates harmlessly before striking him; psychic bolts fizzle into
innocuous sparks and gargantuan chainblades grind to a halt
against this aetheric barrier. (Thousand Sons Codex, 8e)
