Here's a fun secret: The world of Ghost Lines and Blades in the Dark is actually the past of the world of the Wild Blue. We played a Blades series where the PCs ended up creating the Wild Blue and opening the way for the demons to hurl the worlds into the sky. Good times. :)

Also, the demon Setarra is from the original World of Dungeons campaign, in which the PCs broke the gates of death. One of the PCs did it in exchange for immortality. When it was time for our next game series, the players agreed to set it 1000 years later, and Ghost Lines was born. :)

Keith's original WoDu character is the Immortal Emperor. :)
