Gallan's Rock

Space Marines Portal
Ultramarines

Gallan's Rock is a rock promontory overlooking a waterfall in the Crown Mountains on Macragge. It is accessible from the Fortress of Hera, the fortress-monastery of the Ultramarines.^[1]

According to Ultramarines legend, the Rock was where Roboute Guilliman beheaded the rebellious Consul Gallan, who had murdered his co-Consul Konor, Roboute's adoptive father.^[1] The Ultramarines themselves use the Rock as a place of execution, for members of the chapter who have been condemned for serious crimes.^[1][2]
