Following it's attempted desecration and subsequent relocation Slag Valley Bullett #14 The Emperor's Thumb was once again the focus of a conflict, this time loyal guardsmen from the Krablokistan 47th and 420th Suhnnydayl Shithawks battled what at first seemed to be Ultramarines led by their famous Primarch. Despite seemingly attacking one of the Imperium's greatest heroes, the Astra Militarum followed their orders and defeated the Ultramarine force intent on capturing 'The Emperor's Thumb'. During the exchange what was at first believed to be Rouboute Gullimann was killed by sustained battlecannon fire. After the battle it was accertained that it was not Gullimann but a cybernetic replicant of the Primarch and by that reasoning the Ultramarines were renegades intent on theft. Commander Ursakar Creed who was leading the 420th stated "The foul copy of our glorious Primarch is decommissioned! Long live the 420th! Cadia stands! Go on ya good ting!".
The Cloud of smoke denotes a non human aspect of Gullimann.
