It is very important to protect your head underground, so the kobolds made special helmets. They also put candles on them to see better in the underground darkness, as well as to track the movement of air. After the war with the dwarves began, helmets began to be remade into military helmets to protect their heads not only from protruding stones, but also from blows from dwarven swords. When the war ended, the need for helmets disappeared. However, the kobolds did not abandon them, since they turned out to be better than the old helmets. They only added a special place for candles, as it was in peacetime.
