Warhammer 40,000: Marneus Calgar #1, by writer Kieron Gillen, artist Jacen Burrows and colorist Java Tartaglia, hits stores in October, the first title in Marvel Comics' new Warhammer line of a book featuring characters and concepts from Games Workshop's Warhammer 40,000 (40K for short) sci-fi, miniature war game. Ahead of the series' anticipated debut, Marvel has provided CBR with two pages from the issue.

The first page shows Marneus Calgar as a young boy, either during his training to become a Space Marine or just before his trials started. Space Marines Aspirants are typically older children or teenagers, because in order for them to develop superhuman physical traits, their surgically implanted implants must coordinate with natural growth hormones.

The art also shows the Ultramarine tasked with training Calgar and his fellow aspirants. On the wall next to him is a picture of the Emperor of Mankind; the godlike warrior that unified humanity into an interstellar Empire and created the Space Marines, before being struck down into a vegetative state at the end of a galactic civil war.

That event, the Horus Heresy, happened thousands of years ago, but its echoes reverberate in Marneus Calgar's present day, which the second image is set in. In it, Calgar, who has been transformed into a new breed of tougher Space Marine known as Primaris, stands ready in the hold of Thunderhawk gunship. It's flying over what looks to be an Agri-World -- a planetary farm dedicated to feeding the Imperium of Man. He's accompanied by a number of Space Marines and a character who Gillen hinted at previously in an interview with CBR.

That character is named Quintus Heximar and is a member of another of 40K's most fascinating factions, the tech priests of the Adeptus Mechancus. The Admech worship the "Omnissiah," and build and service much of the Imperium of Man's advanced technology.

When Gillen, a longtime 40K fan, spoke with us about the series in August, he described his approach to the book as being comparable to Frank Miller and David Mazzucchelli's Batman: Year One -- a work you can give to someone to explain the Dark Knight Detective, but a comic that is also a tale every single fan of the Caped Crusader can appreciate.

To that end, Gillen says he decided to focus on the past and present-day exploits of one of the most famous members of 40K's most famous type of characters, the genetically engineered, power armor-clad super-soldiers known as Space Marines. The titular character, Marneus Calgar, is the Chapter Master of one of 40K's best-known Space Marine Legions, the Ultramarines; an order of warriors known for their tactical acumen.
