This mighty beast ravaged the earth's military for nearly eight years, slaughtering thousands of human soldiers and civilians. Since it's natural skin was near bulletproof, there was little the humans could do to stop this monster's rein of destruction.
It wasn't until the invent of Drill Rounds that the humans were finally able to slay the massive beast, but at the cost of heavy human casualties.
To this day stories are told of the rein of distruction this beast caused. This made humans fear the Valule species, dubbing them the 'Sand Drakes', adopting the persona of Dragons from human medieval lore.
