"If a tool cannot be turned to the service of the Emperor, it should be destroyed. Thus, I have encouraged my own allies and agents to eliminate these beasts wherever they are found. It seems there is no shortage of foolish heretics who see the Ambull as an opportunity for profit or prestige, only to discover too late that they have damned themselves for little return. The remains of the Quicksilver Palace on Aryus One lie a mute testament to such folly, destroyed by seismic charges placed my own hand. May it serve as an example to others who turn away from the Emperor’s Light."
–From the journals of Inquisitor Felroth Gelt: 719.M41
Aryus One is a feudal world in the Malfian sub-sector of the Calixis Sector. It was the site of a place known as the Quicksilver Palace, which was destroyed by Inquisitor Felroth Gelt for harboring the xenos species known as Ambulls.
