A Strike Force of Blood Angels and Lamenters are thrust into a completely new reality, along with a fleet of Imperial Refugees. But how? And Why? If fate is to be believed, the Emperor has sent the Great Angel's Sons here with a task. They are to protect an infant Mankind from an encroaching Darkness. But even though this galaxy despises everything about them, will they be able to save it? This is a story I have already been making and writing for some time. I originally posted it on FanFiction.net, but I've decided to publish it here as well. I hope you all enjoy it, and feedback is much appreciated! 05/02/2024 I've Returned and published the last of the story I had made originally but now I am releasing my rewrites of another crossover here first, then I will recreate this story afterwards

However something went wrong and a extra primarch was born, the man YN LN would lead the 21st Legion against the horrors of the galaxy. Can he bound with his fellow warlords and unite the galaxy, or will he watch it burn?
