Ira Tempestus

The Ira Tempestus was an infamous event in the history of the Argent Leviathans Space Marine Chapter. In the latter centuries of the 40th Millennium, the Chapter was confronted by a primordial creature of legend - a Revenant Leviathan. This ancient and foreboding creature rampaged across a major coastline of their homeworld of Caerule, slaughtering hundreds of civilians in a nearby hive city. Only the intervention of the Argent Leviathans halted the slaughter of the foul creature, however, their Chapter Master was tragically killed, leaving the Chapter bereft of leadership.

History
Nearing the end of M40 the relatively young Chapter had many victories under their belt, winning countless battles without losing any notable members of the Chapter, this was until the year 923.M40, the day the Great Ocean raged and the Lord of the Tide got dragged away. During 923.M40 the largest storm Caerule had ever seen hit the coast of Kar'Morgh. The one Company of Argent Leviathans attempted to minimise the civilian casualties by getting them to the highest point of the small hive city in order to protect them from the over 30-foot tall waves. However it was not just the waves killing civilians, word quickly spread that there was a monster coming close to the shore of the city, however, believing it was just the talk of simple citizens the brothers of the chapter ignored it.

While evacuating the civilian populace a great shadow began to fall over Kar'Morgh, a sea creature nearly 70 feet at its highest point above the water, a creature later to be recognised as the Revenant Leviathan. After the creature began assaulting the lower tiers of the city, Lord Magister Daethos Kordavius and a strike team of Kraken Praesidio went down the city in attempts to kill the creature. Little is known of what happened to Kordavius after he descended the city, only that he and all of his strike team were killed, but not before slaying the creature from the inside. Now the Chapter was without a leader and Kordavius was later replaced by the commanded First Princeps Vel'hiam Dratus.
