Is this true?

I was at a party last night and I was trying to big myself up a bit by telling people I was LonerBox's biggest fan. One of my friends was really interested and she asked me what LonerBox was like.

I told her that he's a 7'8" giant from the Northern reaches of the kingdom and that it was he who forged the doors that keep the Heart of Winter locked deep within the Black Mount.

I've got to admit that I've only ever listened to a few clips so I'm not too sure what LonerBox is all about. Is what I said true, or did I miss the mark?
