Luna met Sarok back in 2006 in a Magic The Gathering chat room on IRC. They became pretty quick friends and are super close. Their dynamic is pretty fun to watch in the chat sometimes. He was a host for a while back in the 2010s, but Luna decided to bring him back in 2021 for various reasons. (Not the least of which - THAT ACCENT! I mean come on!)

He has some issues, but he's a great guy. Luna calls him her "asshole friend."
Also, it's not ACTUALLY pronounced SAY-rock, but Luna is a bit of a bitch!
