The Burrow Dragons also had their own specialized jargon. Larger Burrow Dragon groups categorized themselves internally into "Shallow Soil," "Deep Soil," and "Stone." Among these, the "Shallow Soil" Burrow Dragons mainly handled the construction of living spaces, external communications, and were also responsible for building various secret passageways for some Heroes. They would switch out their Prosthetic Bodies, disguise themselves as ordinary people, and head to the city areas to wait for the rendezvous with Heroes. The "Deep Soil" Burrow Dragons, on the other hand, always remained underground.
As for the "Stone," they were technicians who mastered complex refining techniques.
Of course, these special names were not for the purpose of "secrecy," there wasn't much need for "secrecy." For the Burrow Dragons, it was a choice of "reshaping culture." Those names, for them, carried a metaphysical sense of belonging and pride.
