“Bye L'Manberg” is about the aftermath of the Doomsday War on the Minecraft roleplay server, the Dream SMP. The song is Dream’s reaction to the end of the war, which happened when he successfully blew up the fictional country of L'Manburg with the help of his friends Technoblade and Ph1LzA and permanently disbanding it.

Dream slightly changed the lyrics from Wilbur Soot’s L'Manberg national anthem to show how happy Dream is about L'Manberg being gone.
