The translation is really good. Quite nice to read. It would be appreciated if the sfx would also be translated tho... I'm very appreciative of the work nonetheless!
Eruseenuando -> Arsinda or Arasvand
Kaaruniru -> Carnir or Curunir ("Man of Skill"; pron. [ˈkuruniːr]), was the Sindarin name for the Wizard that Men called Saruman.
Esubekku -> Esbek
500 women sired from Emperor to Earl/Counts. If the emperor and each king under him has a harem, I guess 500 can be done. It would've been easier if the involved were told 18 years in advance so they could inflate the population with bastards.
If you're still open to name suggestions (dunno, I've just started this series and I see that it has loads of chapters now), I'd say, going by the Japanese names, maybe something like this for the 3 families: Elsenuand, Carnil, Esbek (Esbekh?). And for the crown prince, Rubrit. Aaaah, Elsenuand still sounds weird...
