Tales of Tolgard
The smallest of the giant beetles, fire beetles are nevertheless capable of delivering serious damage with their powerful mandibles. They are found both above and below ground, and are primarily nocturnal.
Despite its name, the fire beetle has no fire attacks, relying instead on its huge mandibles to inflict up to three times the damage of a dagger in a single attack.
Fire beetles have two special glands above their eyes and one near the back of their abdomens. These glands produce a luminous red glow, and for this reason they are highly prized by miners and adventurers. This luminosity persists for several days after the glands are removed from the beetle, and the light shed will illuminate a radius of 10 feet.
The light from these glands is “cold” — it produces no heat. Many mages and alchemists are eager to discover the secret of this cold light, which could be not only safe, but economical, with no parts to heat up and burn out. In theory, they say, such a light source could last forever.
