The Apostasy Gambit
Brother Corteza is an Assault Marine of the Blood Angels chapter of the Adeptus Astartes. Like most of the brothers of his chapter, Corteza is a skilled close combat specialist and is most at home when engaing enemies up close. To this end, Corteza goes into battle armed with a chainsword and plasma pistol- the better for tearing his enemies apart in brutal melee. His power armour is ornamental and adorned with gold trim, elaborate carvings and flowing purity seals. This makes it incredibly impressive to behold but also very hard to hide on the battlefield, not that Corteza seems to be worried.
