Story Choice
What was Texas and Oklahoma are vast divided lands. Not for them the relative unity of Mexico where different nations fight under the gaze of Tlaloc. Not for them the banners of the West Coast where the choice is often between NCR's vassals, the coming of the Legion or the harshness of the Mojave. These lands are wide and not subject to only one threat. Their soil will be swamped with blood at the coming of the age.
Due to Texas being basically torn between at least three narratives, Choose 1
The Butcher's Mission: Caesar son of Mars and overlord of the Legion has spoken. Edward Sallow once of the Followers of the Apocalypse has spoken. He told his greatest agent Lanius the Butcher to go and take the Dog City who was once Denver and subject any lands between Arizona and it to the harsh rule of the Legion. Lanius will do so with glee for he has earned his name a thousand times over. Yet perhaps he underestimates what will test the Legion's strength? On his path are the Executives, raiders still clad in Vault-Tec tattered suits, speaking in the corporate tone of yesteryear while dragging people to their experiments. The Twin Mothers whose tribes revere the ancient Diana and pray to the moon to give life back to the Wasteland, have excited Caesar's curiosity as he wonders how an ancient goddess can be still known in these times. In the ruins robots have awoken running free across the streets of destroyed cities while the Hangdogs live to their name in forgotten Denver having turned the wild packs who infest the roads into their friends and allies. There are even rumors about an underground Chapter of the Brotherhood of Steel, dread paladins in power armor looking greedily to what can be salvaged.
The factions there are all united in their internal disparity. Most are tribals with a single advanced technology to their name like cybernetic dogs, or terraforming, or the strategies of the Legion. The Brotherhood Chapter is spurred into action by the abundance of salvage and ancient technology around while the robots themselves can emerge as the greatest threat of them all.
The Master's Legacy: Long ago lived a man named Richard Grey but this name is not uttered across the land anymore. For he became the Master and birthed the race of the supermutant. He succumbed under the blow of the Vault Dweller when the ashes of the war were still warm and the New California Republic a village beset by raiders. He died but his armies did not spreading north and east, pursued by the vengeful Brotherhood of Steel. The first leader of this legion, the mighty Attis, is dead too and his army has splintered. One of his lieutenants Shale is still faithful to the vision and is perhaps the greatest threat to the region. Against him are not only arrayed the Texan Brotherhood of Steel and the stalwart defenders of Lone Star but also a group of Mutants who have decided to pursue unity in peace. This Unity of Austin is perhaps the only state in all the wastelands where men and women willingly go to the green vats where mutation is perfected. At the edge there are other powers lurking. In a garden of her own creation an albino girl still watches over the wastes. At the border with what was Mexico the Texas' Arms Association are the treacherous vassals of the Republic of Rio Grande. To the east, near the irradiated swamps of Louisiana that was, the Carthaginians, worshippers of the flame and notorious cannibals look with hungry eyes upon all they survey, finding the Brotherhood of Steel worth to get out of these cans they call armor.
In a way this is maybe the simplest experience? Shale's army is the biggest threat to the region but the factions facing him are riddled with internal schisms and problems. At the border the nations have links either to Mexico or Louisiana which means possibilities of intervening in these regions squabbles (Moreso for Mexico as Louisiana is not developed in the mod yet and my own ideas are only Gators and Vodoun)
Death and Leisure: Oklahoma has become a strange land. The self-extermination of many of their neighbors has allowed the First Nations to reemerge as powerful confederations whose casinos are as famous locally as New Vegas in the Mojave. Yet the confederations are not only ruling through caps but by the vast stores of knowledge they managed to keep. Their laboratories and libraries are busy with scholars pondering the sciences who flourished before the war. They are joined by the Last Patrol, ancient ghouls, remnants of the army who once patrolled the state's road. These warriors are always on guard for recently an ancient evil awoke. Immortal psychics long imprisoned for experimentation before the Great War are on the rise. This Chained Choir resounds through the wasteland luring people to their ancient facility to enslave them. Their presence is heralded by nightmares as reality breaks under the strain.
