Balor is from the Celtic/ Norse mythology..

He is the king of a certain race of giants (he is only treated as a God in this LN). Some myths say that with his eye, he can turn anything into salt.

I wonder if Lugh, Balor's son and included in top 10 strongest beings will make an appearance in the series because of Ise's somewhat connection with Balor.
