In the world of Ashura, the Dwarven Kingdoms are a formidable and geographically concentrated race. Known for their physical strength, resilience, and stubbornness, dwarves are master miners and engineers who build vast underground cities in the mountains. While digging deep into the mountains, the dwarves discovered a new type of rock elemental that they would come to call "Pebble." These creatures, similar to dogs, are now kept as pets and trained to fight alongside their dwarven companions in battle.
