For (you guessed it) the world of Aldona. This was a gytan -- a lizard-like herdbeast of the desert regions. They were about cow-sized and just as ponderous. Gytans would have been used to pull wagons, butchered for meat, and used for mounts (if absolutely necessary -- you wouldn't be getting all that far on one). They could retain water, like a camel, and subsisted on the sparse weedy grasses of the savannahs that bordered the deserts. Their thick scaly skin was well protected against the hot desert stands, so they were well suited for the harsh life of the regions. Colored with Crayola pencils.
