The Giant Riding Lizard is originally from the lands immediately South of the Demonsteeth Mountains, but was domesticated by the ancient Lizard People many thousands of years ago, and the two have lived in constant symbiosis since.
Much like a regular lizard, though increased in size until it is truly of gargantuan proportions, these cold blooded reptiles are stubborn, aggressive, have a voracious appetite and hard to train. But despite this, once finally broken in, make excellent mounts for the Lizard People and allow them to traverse great distances at a slow and steady or fast and aggressive pace as the needs of their immediate situation dictate.
Immensely strong, Giant Riding Lizards main weapon is their massive, teeth filled mouths and their strong, leathery scaled skin that turns aside all but the most determined blows.
The only disadvantage is that these creatures take such a long time to breed, and almost as long to train and grow, making losing the mounts something that the Lizard people will avoid at all costs – and become enraged if one of their mounts are killed.
