Mastodon's contribution to the second mixtape for HBO's hit fantasy series Game Of Thrones came about after guitarist Brent Hinds met some of the cast members and one of the writers at the UK Sonosphere festival. Drummer Brann Dailor explained to FasterLouder: "We just kept in touch and they told us about this Catch The Throne mixtape thing. Last year, it was kind of a hip-hop thing, I remember, and they said they wanted to branch out and make it more of a mixed tape and have some other kinds of music involved. And one of the styles they wanted was to include some metal bands." "We were super excited," Dailor continued. "It's one of our favorite shows as a band; we all gather around the TV on Sunday nights after we play our rock show, if the show is in full swing and we're on tour. We get together and watch it. We're big fans. So when the opportunity presented itself, we were excited to be a part of it. We're excited with what we were able to come up with, even if it's not a 'metal' song per se. It's something different."

The title of this dark metal rumination refers to the horrifying and mysterious supernatural beings that exist in Game of Thrones beyond the Wall.
