Didn’t I tell you about my first visit to Peladon?
While monsters and villains have often made encore showings on Doctor Who, the series’ first return to a particular planet—well, one not named Earth or Skaro, at any rate—only comes in Brian Hayles’ “The Monster of Peladon” (Story Production Code YYY), reprising his “The Curse of Peladon” from Season Nine. Hayles took more than just a setting, though; he also carried over the essential plot of his earlier tale, right down to an alien scheme co-opting old Aggedor, the god-beast worshipped by the Peladonians, to acquire the feudal society’s minerals.
The original story stands out mostly for Hayles’ ingenious decision to recast his fearsome Ice Warriors as upstanding, honor-bound members of the galactic Federation, causing much consternation on the part of the Third Doctor, who has all his frankly shoddy detective work undone by their sudden bout of pacifism. Here, the Martian menaces aren’t on hand to help vouch for the Doctor after he re-appears on Peladon some fifty years after his first visit. Luckily for the Doctor, who once again is accused of rank blasphemy for entering the Temple of Aggedor (using the same secret tunnels and doors from five decades prior), the lovable mono-eyed green hexapod Alpha Centauri does show up just in time to recognize his old friend.
Along with Alpha Centauri (who hails from, um, Alpha Centauri) are the Earth engineer Eckersley and the Vegan mining specialist Vega Nexos, all overseeing the exploitation of Peladon’s precious trisilicate deposits; the mineral, used extensively in Federation technology, must be procured in great quantities to assist the Federation’s war effort against the fearsome foes of Galaxy Five (not to be confused with those from Galaxy Four). The constant, and deadly, reappearance of the “spirit” of Aggedor riles up the miners, who, no better treated now than fifty years prior, rebel against Federation influence.
Where before the young king of Peladon fought against the influence of his High Priest, who was being tricked by a Federation envoy into driving away the Federation—the better to allow the envoy’s own planet, Arcturus, to claim Peladon’s rock-bound riches—here, the young queen of Peladon fights against the influence of her Chancellor, who is being tricked by a Federation envoy into attacking the rebelling miners—the better to allow the envoy to traitorously sell the trisilicate to Galaxy Five.
But just to spice things up ever so slightly (and to fill out six long episodes), the traitor this time turns out to be…oh, you’ve probably already guessed.
