Luxon

Luxon are giant, bus-sized, hairy reptiles that are commonly used as pack animals in caravans.
In the wild, their large size allows them to part a significant amount of mist, and by travelling in herds of around seven to fifteen, they manage to avoid most danger that the mist presents; they also have very good natural defenses, them being very large, covered in scales, and able to deliver powerful stomps and kicks, allowing them to fend off most any threat that does reach them.

Luxon are reasonably peaceful animals, although they can be temperamental around larger creatures, and any aggression towards them will be met with immediate retaliation from a herd.
