LIZARD

These reptiles may be an ancestral dragon type or an offshoot of a common ancestor. In any case these creatures resemble red dragons, are sometimes called "false dragons," and the latter seem to avoid confrontation with fire lizards. They are slow-moving creatures and often (50%) sleep for long periods. They are found in subterranean lairs, coming forth every fortnight or so to hunt. 

As shiny things attract them, fire lizards collect metals and gems in their den. There is a 10% chance that the lair will contain 1-4 eggs (market value 5,000 gold pieces each), but the fire lizard does not otherwise care for its young which depart after hatching.

Lizard Mounts are a species of subterranean lizards which the Dark Elven nobles breed. Each lizard has AC 5, moves 15", has
4 + 4 hit dice, and will attack by biting for 2-8 points of damage. These creatures are as Large (L) as a small horse, with longish legs for a lizard. For purposes of mounted attack, treat them as medium horses when a lance is wielded from atop one.

Because of the mouth-size of these creatures, a roll of 20 indicates a minotaur lizard attack has picked up any creature of man-size and weight or less (7-ft or less, 300 pounds or less) and has it fast in its mouth where it will be helpless to attack next round, but where the lizard is certain to be able to bite the creature again.

A variety of giant lizard which is found only underground, the subterranean lizard is most aggressive and dreaded, for it is able to run along ceilings or walls as easily as floors because of its suction cupped toes. 

Worse still, its horrible teeth inflict great wounds, and it can cause double damage on hits where it clamps both jaws firmly on its victim (indicated by a die roll of 20). 

As with most other lizards, it typically drags its prey to its lair before devouring it.
