To Hunt a High Lord

To Hunt a High Lords is the name of the Imperial castigation campaign carried out by the Astral Leviathans Space Marine Chapter in 100-600.M36 against a self-proclaimed 'High Lord' in the Jericho Sector who professed to be a 'prophet' who spoke on behalf of the God-Emperor.

History
The Astral Leviathans Chapter becomes enraged when they learned of a High Lord of Terra daring to say he received a vision of the God-Emperor, who supposedly spoke to him personally. Chapter rhetoric stated that only the most holy of battle-brothers received words or visions from the God-Emperor. Once they had defeated a mighty Ork WAAAGH! in the Segmentum Pacificus, the Chapter quickly cut its way towards the Eastern Fringe and the Jericho Sector to cut down the imposter who ruled in bloody tyranny under false words spoken from heretical lips. The Astral Leviathans also sent three companies to the siege of the Ecclesiarchy fortress, helping to bring an end to the Age of Apostasy.
