Was this real?

I have a friend who swears up and down that there was a lore tab regarding a warlock getting intimate with Hive. He claimed that a warlock got on the dreadnaught before we did and experimented with Hive in an adult manner to see if they could feel emotions. While he was in mid-experiment he was killed by a war priest. For the past several years my friend group has clowned him for this, but I'm honestly curious if this was an actual tab or not. I'm pretty sure it isn't but I'd love to be proven wrong.
