Miral

Miral is the Ultima jungle death world where the Scythes of the Emperor made their stand at Giant's Coffin after Hive Fleet Kraken ate Sotha. Chapter Master Thorcyra and most of the First Company died so a company-strength remnant could escape; Exterminatus followed. This Eastern Fringe pin is that Kraken war, not the Tempestus Miral System.
