Terran fiction.
One interesting side effect of the Terrans arrival was its effect on popular media. Slowly through bootleg copies on jumpships the entertainment of the koprulu sector spread from the periphery as unlike their tech no one cared about concealing it. Even as it granted a deeper understanding of the differences in Terran culture and the unifying themes among all their disparate groups. Such as a recurring penchant for historical anachronism on many worlds as rebellion against the cultural conformity of those who exiled them.
Yet at the same time the nature of Terran history and technology led to a flurry of new ideas and themes in popular literature, movies, and other entertainment. The idea of brave mechwarriors fighting alien invaders had existed as a niche but rarely explored topic among most. With the revelation of two alien species in the distant and unreachable koprulu sector an explosion of speculative fiction and dramatic recreations of koprulu sector history emerged.
This happened in every successor state. Often slanted by regional culture and governmental influence of popular media. Often with the titular military of said nation being the first to hold against an invasion of alien terrors.
In the Lyran Commonwealth interest from noble families led to a surge in naval based fiction. With artificial gravity actually making it plausible to create entire dramas loosely based on Terran cruiser crews. Albeit with even more brocade and decoration in terms of uniform and interior ship design. And the presumption that every captain should have a smoking pipe.
In the Draconis Combine a popular genre grew about centred on the culture of one oceanic planet in the koprulu sector which had developed a love of asiatic fashion and haiku poetry. (The few raiders from that planet while initially flattered eventually considered it to become a little weird. Especially since as time went on people from that planet wound up as named characters in every single Terran centric work in the Combine. Often engaging in melee combat or improbable heroics utilising Viking fighters.)
Some examples to arise from this.
Heavens Devils.
A bio pic series based on an semi authorised biography of Tychus Findlay with contributions from James Raynor ( the latter only agreeing to counter some of Tychus tall tales) covering the early military and then criminal career of the two Men.
Crusade For Liberty.
Numerous movies and other series cover the events of what the Terrans call the Great War. But the one most popular is the Crusade to Liberty series. Made more visceral by the direct inclusion of many portions of combat footage from the Hyperion archives and writings left by the reporter Michael Liberty. The final instalments covering the fall of Tarsonis includes viewer discretion warnings as it demonstrates the sheer horror of a fully industrialised and fortified world being overrun by a Zerg assault.
The only comment on it by James Raynor was a form of grudging respect for the abilities of the actor portraying Arcturus Mengsk. "He got the character so well I wanted to punch him in the face."
Defenders of Koprulu and Legend of the Galactic liberators
Two seperate vid series that served as an example of cultural biases from the Taurian Concordat and Federated Suns. Both cover events of Raynor's rebel movement from three years prior to their arrival over Dumassas. Information from before that time and after the end of the Great War has never been released from Hyperion archives. Both have a great deal of creative liberties and fictional scenarios accounting for that gap and many other left out, obscured or possibly made up parts of the raiders history. Both amusingly Have a fan base among the Terrans for very different reasons and one unifying one of how it seems to irk the raiders leadership.
The Taurian one is more faithful towards the culture of the Terrans. The Taurians tend to see themselves as more akin to the residents of Koprulu than any other. They also tend to focus on how the core worlds of the dominion are oppressing the people of the fringe worlds with more negative depictions of the regime as a whole instead of focusing on Mengsk. There is a greater occurrence of slice of life episodes when the Raiders are doing simple things like gathering supplies, helping out the needy, or just relaxing in the black.
The Federated Suns serial has received some criticism for a subtext of Raynor being shown akin to the second coming of King Arthur who will surely make himself king upon throwing down the evil emperor. Along with an exhaustive emphasis on the combined arms aspect of Terran warfare. Tending to favor large scale action scenes along with practically every single episode having something being blown up stolen or set on fire in increasingly bombastic fashion. Along with appearances or verbal messages from Mengsk cursing Raynor's existence.
Anonymous Terran Marine: "Ok I am pretty sure if we blew up that many ships Mengsk would have been trying even harder to kill us."
The one things followers of both series actually agree upon is the respective episodes covering the assault on the UNN studios on Korhal and the subsequent airing of Mengsk's crimes to the entire sector. In that watching old Arcturus finally lose his shit completely never gets old.
