I'm a relative know-nothing to the 40k setting, and was wondering if there have ever been cases where humans (guardsmen, astartes, or other) have ever had romantic relationships with alien races? I mean I've seen plenty of reels, art, and other media depict it, but let's be honest; those aren't exactly credible sources.

Edit: Thank you all for informing me on this matter. It was just a thought I had and I'm happy with just how many of you indulged it. Once again, thank you.

Can someone attempt to make a Minecraft skin for me? My idea is a guy with an all-blue head, with exception for the eyes and mouth, and he wears a grey hoodie, but I give full creative freedom. I've never been particularly good at it myself despite my numerous attempts, so I'm in no place to dictate any of your potential interpretations. Please and thank you, my friends.

(Edit) I should also add my working username outside of reddit is Pixel Plexus, and typically orient my attempts around it.
