6 decades books

This is going to be a Tensura and Warhammer 40000 hypothetical crossover fanfiction series. I''''ll try to provide lore-accurate descriptions while also keeping things fairly entertaining, or so I hope to achieve. This is merely an introduction. Feel free to discuss the direction you think this story should take since I''''ve yet to decide that myself. This was an idea I found myself exploring one day, like, "Oh, this crossover sounds cool", and there were often things in both universes that I didn''''t quite agree with. As for the ones that I did like, this story works as the perfect platform for my self-insertion, as I believe we all love to do. I''''ve been following Tensura for a while. That said, I am new to Warhammer 40k myself, and all I have with me are a couple of novels to go off of. So it should be fun self-inserting myself into Rimuru''''s shoes as I enjoy reading said novels or any new acquisitions, for that matter. So here I am, currently writing this story. I do have my original stories, but due to my personal bias on worldbuilding aspects, it''''s currently stuck dead in the mud, and it will be a while before I can get back to writing them again. So I''''ll be here for a while since it''''s all for relaxation anyway. Please don''''t expect any regular updates. The synopsis goes as such, It''''s been three hundred years since the Tenma War. Due to his immortal lifespan, he''''d often find his days repetitive. So, occasionally every few decades, he''''d take a long vacation and explore different worlds/universes. This is merely one of those trips, and it''''d land him somewhere in the Milky Way galaxy in the grim darkness of the far future. Yeah, I know the plot sounds dumb, so please don''''t sweat the details too much. Also, since 40k is grimdark, there might be some things you find hard to accept or uncomfortable to read, not necessarily NSFW stuff, but close. Fair warning!
