The name Ita Eterno, just like Charita Gil, is from the name of my mother, Charita G. Merino. She was Charita Esternon Gabito before marriage. Ita was her nickname, and Eterno is clearly from Esternon. The Spanish word eterno means eternal in English.
I am trying my hand at writing horror, sci-fi, and fantasy, and I plan to use Ita Eterno instead of Charita Gil.
