Planet of Bones (short story)

 was an illustrated short story in the 1968 Doctor Who Annual, featuring the Second Doctor, Ben and Polly.

Summary
The Doctor, Ben and Polly land on what appears to be an idyllic world. So peaceful does it seem that Polly immediately dubs it "Heaven". After some exploration, Ben discovers the world is inhabited. The TARDIS crew go to meet the locals, near-Humans dressed in what resemble Greek clothing. They speak musically and stop the Doctor and his companions from bickering with each other. This world, it turns out, is actually named "Harmony", and they wish to ensure the name is accurate.

At first, the TARDIS crew are amazed at the sumptuous treatment they're accorded. But as the Doctor begins to ask questions about the word, he encounters some nonsensical answers. Their hosts claim not to have either animals or farms. While his companions are sleeping, the Doctor determines to figure out how the locals derive their nutirition. What he discovers is a rather gruesome room filled with heads. When his presence is detected by Alba and Sandor, they tell him that their world once did have animals, but they died out long ago. Now they wait for people to come to their planet, so they can harvest them.

Sensing he is in immediate danger, he pulls his recorder from his pocket, and begins to play discordant notes on it. The locals are all physically stunned by this disharmony. The Doctor runs to the sleeping quarters to retrieve Ben and Polly. Still using the recorder for protection, the trio manage to find their way back to the TARDIS and depart. Ben and Polly never find out exactly why the Doctor rushed them off the planet, because he judges them "too young" for the awful truth.

Characters

 * Second Doctor
 * Ben Jackson
 * Polly Wright
 * Alba
 * Sandor

Continuity

 * The second Doctor and Ben are shown to have an especially contentious relationship here, perhaps because the second Doctor is generally characterized throughout this annual as being considerably more like the televised first Doctor.   At one point, the Doctor threatens to abandon Ben "in some world filled with loathsome monters [where] you may begin to feel at home at last."  Their extreme discord, however, is a essentially a plot device.
 * Polly calls the planet on which they land "Heaven", but she means it metaphorically. Heaven is, however, an actual planet within the DWU, visited by both the seventh Doctor and Bernice Summerfield, and, at different times, a base of operations for Humans, Draconians and Daleks. (NA: Love and War, BFBS: Death and the Daleks)
 * The Doctor assigns the world the name of "Arcady". Where he gets this name from is unclear, but it shouldn't be confused with Arcadia, an oft-mentioned world by the tenth Doctor and eleventh Doctors. (DW: Doomsday, Vincent and the Doctor)
 * The actual name of the planet, at least according to its inhabitants, is "Harmony".
 * The Doctor suggests the Milky Way is his home galaxy. This is consistent with later Doctor Who fiction, but the preferred Doctor Who term is "Mutter's Spiral". (NA: Human Nature, EDA: Alien Bodies)

Timeline
In broad terms, this story must occur between DW: The Power of the Daleks and The Highlanders. More precise location is difficult, because there are no continuity references in the story. However, placing it in "table of contents order" of the 1968 annual is reasonable enough. Thus:
 * This story occurs after DWA: Only a Matter of Time
 * This story occurs before DWA: When Starlight Grows Cold
