History:

(Warhammer 40,000: Marneus Calgar#1 (fb) - BTS) <centuries before the main story> - Born to the richest house on Nova Thulium and served by the helot Tacitan, Marneus wished to become a space marine, which involved a rigorous testing process that less than 1% achieved. Marneus father hired the renown trainer Crixus to help Marneus achieve this end.

(Warhammer 40,000: Marneus Calgar#1 (fb) - BTS) Marneus was known for stating, "Anyone can quote scripture; the point is to make it live in your heart."

    Chafing under taunts from "friends" Kato and Severan that he gained everything he had from his parents' wealth and that anyone could achieve what he accomplished with such privileges, Marneus used his entire inheritance to also pay for similar training for Kato, Severan and Tacitan. The boys were all approximately 11 years old.

(Warhammer 40,000: Marneus Calgar#1 (fb) ) - Marneus bested Severan in a contest of first blood, acting defensively until manipulating him for a simple strike. Severan stated that he had had Marneus retreating for the entire duel and that if it had been a fight, he would have won and that he was the warrior. Marneus reminded him that warriors fight the battles they are given, not the ones they wish. Both Kato and Severan mocked Marneus' privilege and sanctimonious nature, at which point Marneus announced to them that he was paying to have his trainer train Kato, Severan and Tacitan. >

    Kato ridiculed Marneus' decision to include a servant when such blade tutors were for noble sons, but Marneus reminded him of his point that the honor of being a space marine should not be bought by mere privilege. Even Tacitan told Marneus that he did not need to do this and that it was too great an expense, but Marneus reminded him that the master made the decisions and further advised him that he would not thank him for what lied ahead.

    The group then met Crixus, who told them that , though he had failed to become a space marine, he had been charged to train others from the mistakes he had learned, and that he had sworn an oath that his life was forfeit if any of his charges were rejected: All who trained with him would either become neophytes of would die. He then took them to Nova Thulium's smallest moon habitable moon, the harsh Thulim Minor, after advising them that they had just short of a year before the marines arrived to take their aspirants. He started their test immediately, dropping them off and challenging them to outrun the Ambull and meet him on the other side of the valley.

(Warhammer 40,000: Marneus Calgar#2 (fb) - BTS) - Kato suggested hiding in the tunnels, but Marneus remembered hearing something about the Ambull boring through the Earth to find its prey. Seeking something else upon which the Ambull might feed, the quartet ran through a den of wolves. Although the wolves went after them, the Ambull went after the wolves, and the youths got away. Severan was attacked by either a wolf on the Ambull, and Marneus pulled him free, although Severan received a deep cut on the right side of his face/head.

(Warhammer 40,000: Marneus Calgar#2 (fb)) - Severan and Kato accused Marneus of deliberating waiting until Severan had been slashed thusly before helping him. Regardless, they made it to Crixus, who congratulated them, noting that all four surviving the Ambull was rare. Crixus then gave them their first two lessons: taking shifts manning the "heavy stubber" (a large gun atop their base); and how to seal a wound with a blow torch.

    Marneus and the others were trained to fight off the wolves with anything with a sharp edge or anything that could be used as bludgeon. They enjoyed the honing of their martial skills.

    Less enjoyable was the "hardening of the soul: Pain to burn away pain." Tasks to make them strong. Tasks to make them stand straight together.

    They were left overnight, one exposed to the cold to survive, bound, while the others guarded them; with swapping each night.

    As the months went on, other aspirants -- those that outran the Ambull -- joined them, with most dying out progressively, but their numbers did slowly grow, and those who survived grew strong and grew together. However, Marneus and Tacitan seemed to lag behind somewhat, and when they came in from a run long behind the others, Crixus sent them to run it again, and Kato and Severan continued to mock Marneus, with Severan noting that he was broken and would soon be dead.

    On the next run, Marneus and Tacitan slew a pack of wolves that attacked them, and Tacitan told Marneus that he knew he was slowing him down and that Marneus could match Severan and Kato without him. When Tacitan told Marneus to leave him if the moment came when his strength failed him, but Marneus helped him up, telling him that his strength was his brother beside him and that no marine would ever leave a brother. Taking Marneus hand to help himself back to his feet, Tacitan told Marneus that he was a born leader and that while he could fail himself, he could never fail Marneus.

    Marneus and Tacitan found spiritual strength in each other, but they observed how Severan and Kato found a strength for physical. When Marneus and Tactican asked Crixus how they could become larger and stronger like them, Crixus told them to ask them. However, looking upon Kato and Severan, Marneus and Tacitan found them to be animalistic killers.

(Warhammer 40,000: Marneus Calgar#2 (fb) - BTS) - The night before the Angels of Death were to begin the actual aspirant selection, Marneus and Tacitan stayed up late, talking about what it would be like to see one of them, but eventually they slept.

(Warhammer 40,000: Marneus Calgar#2 (fb)) - Awakening to find all of their peers gone, Marneus and Tacitan tracked them into the tunnels into which Crixus had forbade them to enter. Motivated by their peers' prior entry, Marneus and Tacitan avoided traps along the way, passing through corroded and blasted remnants of an old base before coming upon a cultist ritual over a black altar. They were then confronted by Crixus, who swiftly battered the two of them unconscious.

    As Severan restrained Marneus, Kato and a four others held down Tacitan on the altar, as Crixus revealed his true past and motivations in preparations to sacrifice them both.

    Crixus stated that though he had passed every test and was the finest warrior of his year, he was considered too pure of a killer to be a space marine. After spending decades training warriors for the false emperor, Crixus saw visions and apparently learned the truth of Lord Khorne.

    Crixus further explained that slaying Marneus and Tacitan was the final test for the six. When Severan told Marneus if he begged that he would make it quick, Marneus instead smashed his head back into his nose, after which he leapt on the altar and helped Tacitan fight off the others. However, Crixus then stabbed Marneus through the back and out through his xiphoid region.

    Tacitan grabbed Marneus and leapt off a cliff into the water below. Tacitan pulled him to the edge and told him they would close his wound, but Marneus knew that it was over and his last words were, "Marneus Calgar will never be a Space Marine."

    Unwilling to accept this, Tacitan resolved to take his friends name -- who had saved his life so many times -- to honor it and become a marine.

    Courtesy of Loki, who gave me the background on Warhammer 40,000 and recommended profiling this Marneus Calgar to represent that series:

    Warhammer began as a tabletop miniatures wargame launched in 1983 by British company Games Workshop - if you are unfamiliar with tabletop miniatures wargames, imagine the people who reenact Civil War battles using figurines. Games Workshop itself was launched in 1975 and initially manufactured boards for games like backgammon, but within a few years they got involved with the growing role-playing craze that had started with Dungeons & Dragons. Games Workshop became the official UK distributor for TSR, the company that owned D&D, and then got the license to reprint several other American RPGs, as printing copies in the U.K. was cheaper than importing the American editions. They also co-founded Citadel Miniatures, releasing small lead figures that could be used for those RPGs, and in 1977 began publishing the U.K.'s preeminent RPG magazine, White Dwarf, still in publication today. In 1983 they realized that rather than just reprint other people's games under license they could produce their own - though they still continued to do reprints too. Warhammer was their first game, though at that point as mentioned a miniatures wargame rather than RPG. Their first RPGs were the superhero RPG Golden Heroes (which was illustrated by some famous comic artists including Brian Bolland and Alan Davis), and then the first Judge Dredd RPG. In 1986 they made a RPG version of Warhammer, titled Warhammer Fantasy Roleplay, set in a world inspired by Lord of the Rings, Elric, etc. In 1987 they released Warhammer 40,000 (commonly abbreviated to Warhammer 40K or just 40K), switching out the fantasy setting for an excruciatingly grimdark SF setting - though still with all the standard fantasy races like Elves, Dwarves, Orcs, etc., just with a SF patina added to them. 

    The first Warhammer novel, The Other, was released in 1989, and the first 40K novel, Deathwing, in 1990. The first (AFAIK) Warhammer comic was Warhammer Magazine, published by Games Workshop themselves from 1998 through 2004; Boom Studios took up the license and published a number of one-shots and miniseries from 2006 through 2009; Titan Comics had their run from 2016 to 2018; and finally Marvel in 2020 and 2021. Oh, and there was a 40K animated movie, Ultramarine, released in 2010.

    The titular Marneus Calgar is a high ranking Space Marine, first introduced in White Dwarf#97 (January 1988), and created by David Wise and Rick Priestly. His first comic appearance seems to be in Boom's Warhammer 40,000: Defenders of Ultramar#1 (2008), but there might be earlier ones, as the Warhammer comics don't seem to have been properly indexed anywhere I can find. - this is the guy who reveals he was born Tacitan and took his friend's name. He's the main focus of the miniseries and has been around in the Warhammer 40K mythos for decades.
