Getting a hold of the latest products for Warhammer 40,000 can be tricky, given the game’s huge surge in popularity. But getting vintage 40K products — known as OldHammer to collectors — is even harder with sought-after models and rare books selling for huge mark-ups online. So this weekend Games Workshop is throwing us a bone (likely part of a skull) and reprinting the original rules for 40K, first released in 1987. The print-on-demand run of new old books begins Oct. 14 and runs through Oct. 23, according to a news release.

First published in 1987, Warhammer 40,000: Rogue Trader introduced the world to the genetically enhanced child soldiers known as Space Marines and their deeply corrupt theocratic fascist overlords, The Imperium of Mankind.

Primarchs weren’t god-like super soldiers either, but merely renowned leaders drawn up through the ranks from common Space Marines. Aside from those heresies, however, the tone and timber of the text itself feels quite of-the-moment lore-wise thanks to author Rick Priestley’s epic turn of phrase:

For more than a hundred centuries the Emperor has sat immobile on the Golden Throne of Earth. He is the Master of Mankind by the will of the gods and master of a million worlds by the might of his inexhaustible armies. He is a rotting carcass writing invisibly with power from the Dark Age of Technology. He is the Carrion Lord of the Imperium to whom a thousand souls are sacrificed every day, and for whom blood is drunk and flesh eaten. Human blood and human flesh — the stuff of which the Imperium is made.
