Why did the glory of the king say that Arthur's first friend list was the Lich King?

Because Arthur has a skin named Death Knight, and the Lich King is another death knight in World of Warcraft, there will be related lines when designing lines. This "first friend list is the Lich King" is one of them. This sentence may be a tribute to the world of Warcraft, so it is said.

Old Arthur's hero is set as a paladin, so it has always been a bright and just image in the hands of players. The beauty of this death knight's skin is probably to make the opposite effect, so Arthur blackened into a death knight. Guardian of justice, holding the sword of justice. The other doubts justice and associates with the Lich King. So this has something to do with the Lich King.

Because of the tribute element, Arthur, the death knight, will list the Lich King at the top of his friends list, because that is the person whom the death knight worships.
