Well, in the context of Warhammer, there are often dark and menacing forces. This 'ratkness' might be a new and unique threat. It could involve battles in different terrains, like the dark alleys of a city or the desolate wastelands. The fanfic might explore how the heroes gather their strength, weapons, and allies to combat this 'ratkness'. They could be facing not just physical threats but also magical or psychological ones.
I'm not sure as the term 'lught' seems misspelled. If it's 'light', it could be about Don's adventures in a world filled with elements of light, like a magical realm where light has special powers and Don has to face various challenges related to it.
There are many alternatives. One could write adventure stories where heroes embark on quests in the Warhammer universe. Another option is to create fanfic focused on the strategic battles, exploring different military campaigns and tactics.
I think Warhammer 40k fanfics are a great way for fans to explore the vast and complex universe further. A good fanfic can add depth to the existing lore. For example, it might focus on the daily lives of the Imperial Guardsmen, which we don't often get to see in the official works. But there are also those that are just not up to par. Maybe they lack proper grammar or have a really convoluted plot that doesn't make sense in the context of the 40k universe.
A specific Warhammer 40k fanfic could either be a masterpiece or a disaster. If it manages to capture the essence of the 40k universe, such as the scale of the battles, the complex politics between different factions, and the religious fanaticism that pervades the Imperium, it's likely to be a good one. However, if it goes against the established canon too much or has a poor writing style, it won't be as appealing.
One factor could be overly melodramatic characters. For example, a Space Marine who constantly spouts cheesy one - liners in every situation. Another might be when the fanfic completely misrepresents the lore of the Warhammer 40k universe. If it has a character using technology in a way that goes against the established rules of the setting, it can come across as cringey. Also, bad writing like poor grammar and lack of proper pacing can make a fanfic cringey.
One popular 'warhammer fanfic' story could be those that focus on the Space Marines. For example, there are fanfics that explore the backstories of individual Marines in a particular chapter. Another type might be the ones centered around the battles in the Warhammer universe, like the epic clashes between different factions. There are also fanfics that delve into the relationships between different characters, whether they be allies or enemies within the context of the Warhammer world.
