Leontus had spent two exhausting months pushing the front into The Contested Zone.
The whole of Segmentum Pacificus had descended into chaos. The Tyranid bio-fleets had bypassed the entire Night World and begun attacking its surroundings with wild abandon. The surrounding fronts were pushed back again and again, then reclaimed with the help of reinforcements.
Imperial Regent Guilliman had learned of the situation here. After he personally took command in Segmentum Solar, the reinforcements he provided brought some relief to the fighting.
Yet this had made no substantive difference.
The Firewall Plan implemented by the Adeptus Custodes had failed to take effect.
Over a thousand planets had been destroyed by exterminatus, their entire surfaces burned to ash.
Yet the three tendrils of Leviathan seemed to ignore this cordon, which stretched across almost all of Segmentum Pacificus, and simply kept advancing.
More and more troops were transferred here to stabilize the situation. Segmentum Tempestus, the only segmentum where the fighting was relatively quiet, had even been stripped of large numbers of troops to reinforce the Imperial forces in Segmentum Pacificus.
Yet they faced three Leviathan tendrils and a vast armada of tens of thousands of bio-ships.
Even with reinforcements, Segmentum Pacificus could barely hold the enemy to a stalemate.
Bloody battlefields like meat grinders played out across the entire Star Region every second of every minute.
From brutal battles in space to bloody struggles over planets, everything echoed with the dying screams of humanity.
The Segmentum Departmento Munitorum had even opened the Navy's ship reserves, bringing countless naval vessels built untold years ago into service one after another.
To ensure they had enough personnel, the Navy's first task after every battle was to search damaged ships for survivors and rescue them.
The Imperium's strength was being rapidly consumed on this battlefield.
