Fortress of the Sigillite
The Fortress of the Sigillite is a region of the Imperial Palace.[5a]
History
The fortress was used by Malcador the Sigillite as his base of operations for the Chosen of Malcador and repository for the most precious items of the Sigillite Order.[5a] After the death of Malcador in the Siege of Terra, the Fortress was badly damaged but quickly restored to operation under Khalid Hassan. With the clandestine approval of Rogal Dorn, Kyril Sindermann was able to help organise a new forbidden archive of texts related to the Warp within the Fortress in order to combat another Heresy in the future.[5b]
When Khalid Hassan was made the new Grand Master of Assassins, he worked with Sire Vanus to turn the Fortress into a new powerbase.[5c]
