Continued in Thor Annual (Marvel, 1966 series) #19's "The Flame and the Lightning".
The story's splash pages have the title "Strangers on an Astral Plane" and then two banners: "A Compact in Two Parts: Part the First" and "A Flame Extinguished". No second part is announced in the story (or in the follow-up in Thor Annual #19), and the table of contents titles this sequence "Strangers on an Astral Plane".
