This runestone is beaming with dazzling light. When it is exposed to air, the surrounding temperature sharply rose, discouraging anyone from getting too close. Even from a distance, you can feel the suffocating heat. As for its origin, there has been a variety of controversies, some say it is a star's core after its collapse, or the power source of the lord of Land of Machines? However, all these do not matter, for you clearly know that putting it into the airship's power furnace can turn it into an invincible weapon of war!
