Apex

Apex was both a volcano on the planet Pelegeron IV and a fortress built within the volcano.^[1]

The Apex volcano was noted as being one of the largest such features known across the entire galaxy. It was gigantic in scale - larger even than the legendary peak of Olympus Mons on Mars. When a Chaos Cult arose on Pelegeron, Apex was transformed from a staunch Imperial bastion into the Cult's main stronghold. It was the cult's final fallback point when the Imperium launched the Vinculus Crusade to purge the cult. Both the fortress and a large portion of the volcano itself were destroyed in the Battle of Fire and Blood.^[1]
