One interesting story could be about a Chaos Space Marine who starts as a low - ranked follower but through a series of dark deeds and battles, he rises in power. He manages to steal an ancient and powerful artifact from a loyalist stronghold, which earns him great favor among the Chaos Lords.
A story where a group of Black Crusade players managed to turn a previously loyal Imperial world into a Chaos - ruled hellhole. They did it by manipulating the planet's religious leaders and causing civil unrest. It was memorable because of the elaborate schemes they used, like spreading false prophecies and causing famines to make the people lose faith in the Emperor.
One interesting Black Crusade story could be about a lone Chaos Space Marine who manages to infiltrate an Imperial stronghold. He uses his wits and the powers granted by the Chaos Gods to cause chaos within. Another might involve a group of heretics banding together during a Black Crusade, each with their own motives for following the path of Chaos. There are also stories of battles where the forces of Chaos face off against the Imperium in epic and brutal confrontations during the Black Crusade.
There could be a story where a group of Black Crusade warriors uncovers an ancient and powerful artifact. This artifact could be a weapon or some kind of relic with the potential to change the balance of power in the ongoing war. They then have to fight off other Chaos factions as well as Imperial forces who also learn about the artifact. The whole process involves a lot of battles, betrayals among the Chaos ranks, and unexpected alliances.
One interesting story could be about a superhero who starts as a nobody in the board game. He has basic powers like super strength but not much else. As the game progresses, he faces a series of challenges. He has to stop a villain from stealing a powerful artifact. Through clever use of his strength and some strategic alliances with other heroes in the game, he manages to not only stop the villain but also discovers a hidden power within himself, which is the power of flight. This changes his whole status in the game world and makes him one of the most respected heroes.
One common story could be about the ponies working together to save their homeland. Maybe there's a dark force threatening Equestria. The ponies, such as Rainbow Dash with her speed and Fluttershy with her ability to communicate with animals, combine their skills to fight off the bad guys and restore peace.
One Dread RPG game story could be about a group of adventurers in a haunted forest. They had to face shadowy creatures that lurked in the dark. Every time they made a wrong move, the GM would make them pull a block from the Jenga tower, adding to the tension. In the end, they managed to find an ancient amulet that was the key to banishing the evil in the forest.
One interesting anime tabletop rpg story is about a group of adventurers in a world inspired by a popular mecha anime. They each controlled a unique mecha and had to fight against an alien invasion. The battles were intense, and they had to strategize based on the different abilities of their mechas, just like in the anime.
In some Black Crusade stories, we see the internal politics and power struggles within the Chaos legions. For example, different warbands might compete for resources or try to gain the favor of a powerful Chaos lord. A particular warband might try to complete a specific mission during the Black Crusade to prove their worth, but they face betrayal from within their own ranks as another warband tries to undermine them for their own gain. This complex web of relationships and betrayals makes for very engaging stories.
I'm not entirely sure specifically as I haven't read every story in it. But generally, in Black Library works, there could be tales of heroic battles, epic quests, and the struggles of different factions in the Warhammer universe.
In black code stories, there might be tales of resilience. Maybe a story of a family who managed to preserve their culture and identity despite the restrictions imposed by the black codes. They passed down traditions, values, and skills from one generation to another, which was a form of resistance against the oppressive system.
