The Horus Heresy: Vengeful Spirit

‘And therefore is the glorious planet Sol

In noble eminence enthroned and sphered

Amidst the other; whose medicinable Eye

Corrects the ill-aspects of planets evil,

And posts, like the commandment of a king,

Sans check to good and bad: but when the planets

In evil mixture to disorder wander,

What plagues and what portents! what mutiny!

What raging of the sea! shaking of earth!

Commotion in the winds! frights, changes, horrors,

Divert and crack, rend and deracinate

The unity and married calm of states

Quite from their fixtures!’

– attributed to the dramaturge Shakespire (fl. M2), cited in The Prophecy of Amon of the Thousand Sons (Chapter III, Verse 13)
