The Sword of Kings is a weapon Dartz used in the Battle of Atlantis.

Dartz collected the sword by raising his arm and calling for it. A bolt of lightning came down and transformed into the sword at his hand. Dartz threw the sword at Timaeus, who was in his dragon form, taking out his left eye.

In the English anime, shots of the sword in Timaeus' eye are removed or edited to erase the sword.
