Siege on Hellebrin Headquarters

The Siege on Hellebrin Headquarters was an operation led by the archdemon Mammon, the aim of which was to damage the Foundation's morale and thin out their ranks with speed and precision. The battle is notable as it features the first use of Lucifer's Blitzkrieg army (made up of undead Husks) in the field. It was largely successful, taking out a significant number of Hellebrin's forces, namely three of the senior members of the Round Table.
