Dwarves are learning engineering for centuries. Over the years, two main engineering schools separate from each other: the School of Technics and the School of Sapers. Sapers specialize in conducting of sabotage in the enemy camp. Small and nimble, they can easily penetrate into the back lines of the enemy, to make his life very difficult.
Establishing teleports, Sapers helping the allies to instantly move to the strategic locations, and a variety of mines in their arsenal are designed to protect the conquered territory from enemy attacks. To build theirs smart devices, sappers use large two-handed hammers, which are also powerful weapons in the melee.
Since time immemorial, the dwarves are under the auspices of Krom - the God of knowledge. He gave them extraordinary technical ability. This little proud race compensate for the lack of its growth and strength with the wonderful engineering machines. Under the heavy vaulted stone labyrinths work is boiling hot. Ore is converted into the steel, into the weapon, and cars.
The most skilled Sapers learned to establish contact with Krom directly, raising the battlefield totems, through which their deity sends them his energy. This allowing the dwarves to leave the caves and fight the enemies along, fed by the divine power.
