As Lord Commander Primus, Eidolon leads the Emperor’s Children in the absence of his primarch - who even knows where the daemon prince Fulgrim resides, now? But a challenge from within the Legion forces Eidolon to confront one of his rivals, the ambitious Archorian, a capable officer and tactician who would see the Legion returned to glory. Dissent is unacceptable. It is time for the Kakophoni to be set against their erstwhile brethren. With their primarch obsessed with, shall we say, other matters, the Emperor's Children turn to infighting, in a typically extreme way… Written by Chris Wraight. Running time 25 minutes. Performed by Gareth Armstrong, John Banks, Steve Conlin and Luis Soto.
