Underwater Explorer Helmet

It's very dark at the bottom of the ocean. In addition, the water does not allow you to keep your eyes open for a long time. Nerod could not find a solution to this problem, so he turned to the spirits for wisdom.
 
They suggested that with the help of magic you can create a helmet that can shine. But they also warned the demon that the invention would cause the death of the researcher himself.
 
Nerod did not believe in the prophecy of his own death. He created the helmet of an underwater explorer, with which he studied the ocean floor. But, as the spirits predicted, he died because the light of the helmet attracted the predator Tiburon.
 
No one continued the work of Nerod because of the danger of being eaten by Tiburon. Therefore, today the helmet has become an artifact that reminds everyone of the ambitious demon explorer.
