DW Monsters: Ogri

The next few stories, taking us through the remainder of season 15 and into season 16 are:

• Underworld – the enemy here is a unique one, a computer that has built its own robots.
• The Invasion of Time – other than the Sontarans, this features the Vardans, who have powers of telepathy and teleportation and can turn insubstantial but otherwise basically appear human.
• The Ribos Operation – The only ‘monster’ here is the Shrivenzale, a local predator. From what we can tell, there is little to suggest that its game statistics would be radically different from, say, a tiger.
• The Pirate Planet – This story does not feature a monster.

This brings us to The Stones of Blood. This features three different types of alien. Apart from their physical appearance, the only significant difference between Diplosians and humans is that the former are essentially immortal. The Megara are microcellular machines, more of a game effect than a ‘monster’ in the RPG sense. 

That leaves us with the titular monsters of the story, the Ogri. Although they have since been mentioned in passing, the Ogri are a one-off monster on the TV show. They have made brief appearances in the spin-off novels, although not so far in the audios… at least partly, one assumes, because they are silent. 

DW Monsters: Kastrians

The primary antagonist in The Masque of Mandragora is not only a unique entity, but one that’s more of an abstract threat than something we could stat up; it produces visible effects and controls people, but it doesn’t really qualify as a “monster”. Following that story, though, is The Hand of Fear and Eldrad. Now, Eldrad himself is also unique, in that he’s the last surviving member of his species, the Kastrians, but because we can throw time travel into the mix, that doesn’t mean we could never meet another. Having said that, the Kastrians do not return, or even get much of a mention, elsewhere in the TV series. Indeed, their only other appearance to date is in the audio story Eldrad Must Die! which is, of course, a direct sequel.

DW Monsters: Gelth

The third story in the revised series is The Unquiet Dead, for which the alien menace are the Gelth. They are a one-off monster in the TV series, and, apart from a few minor mentions here and there, have only appeared once since, and that in a short story, rather than anything more substantial.

Description and Biology

We are told that the Gelth were originally regular organic beings. They somehow lost their physical bodies during the Time War, becoming gaseous instead. How this would work is obviously unclear, but, in fairness, we have little idea from the TV series of how exactly the Time War was fought or what the weapons brought to bear in it were capable of.

D&D Monsters: Xorns

Xorns are an original creation of D&D, with no particularly obvious antecedents. The name was almost certainly chosen so that the 1E Monster Manual had at least one monster for every letter of the alphabet... the same is probably true of the quasit. Which, other than that it's a monster largely built around defence rather than offence, is about all one can say about the general concept.

1E

The original xorn has a barrel-shaped body covered with scales that basically take the form of roof slates, and are likely made of a similar, if less fragile, material. It is notable for its (mostly) triradial symmetry, something that makes it look particularly alien. It has three legs, which seem to lack knees and are similarly covered in the armoured stone scales - if anything, it's a wonder it doesn't move even more slowly than it does. The arms look to be less heavily armoured, and are clearly more flexible; they're positioned above the spaces between the legs rather than directly above the hips. 

D&D Monsters: Salamanders

Salamanders are, of course, real creatures - long-tailed amphibians with a vaguely lizard-like appearance. The Ancient Greeks and Romans attributed a number of magical abilities to them, some of them related to fire, but it's clear that they were describing the real animal when they did so. In the Middle Ages, however, there's more of a split between the amphibian and the fantastic creature, with the latter taking on more exotic forms and powers. This culminates in the 16th century with Paracelsus adopting the name for what he termed "fire elementals" and it's this that's most likely the inspiration for the D&D monster.

1E

The salamander in 1E is roughly humanoid from the waist up, with the legs replaced by a single tail that keeps the creature in broadly human proportions. A series of narrow frills extends along the back, and also down each of the arms; these are partially erect, but whether they are buoyed aloft by hot air or are self-animated tendrils isn't something we can determine from the picture. The head has a flattened cranium and a triangular jaw with sharp carnivorous teeth. The ears are significantly elongated, with further frills on them and a pair of branching tendrils project out from either side of the nose, which we might suppose to be sensory. The creature has a partly striped and partly mottled pattern, with the background colouration shading from yellow to red along the length of the body.

D&D Monsters: Efreet

Ifrit are a type of demon in Islamic folklore, associated with the jinn, and in some cases having similar powers (such as the ability to grant wishes), although their exact relationship is nebulous. They are associated with the underworld, fire, and smoke, and are generally hostile. This explains many of the attributes of efreet in D&D, which are specifically described as the fiery counterpart to djinn. (The idea that therefore must be watery and earthen versions of the same thing does not appear in the original Monster Manual, although it was introduced later during the 1E era, with the name "marid" being borrowed from another kind of Islamic demon, and "dao" seemingly being original to the game).

D&D Monsters: Djinn

The djinn originate in Middle Eastern mythology; they are typically associated with Islamic beliefs today, but pre-date that religion. They were originally human-like beings with magical powers, perhaps associated with a creation preceding that of humans and, at least by Islamic times, were regarded as neither inherently good nor evil. In modern western culture, they are mainly thought of as granting wishes and being trapped in lamps, ideas that come from an 18th-century edition of One Thousand and One Nights, although the specific legend is presumably older - they are not part of the original concept of djinn.

In D&D, djinn are described as powerful inhabitants of the Elemental Plane of Air, since many  (although by no means all) of the magical powers associated with them in myth are linked with the air. In the game, the alternative Anglicised name for the beings, "genie", instead refers to a broader category of being, of which the djinn are merely one of the most common. While the wish-granting, oil lamp dwelling, sort of djinn are stated to exist in the universe they are, at best, extremely rare and not typical representatives of their kind.
