Hi are you still contemplating this? Because I've been looking for someone to talk renaming with...

Viera forest names names seem to be Scandinavian inspired. So we have lots of options there. Asta and Tähti are popular even these days and fit the trend of 1-2 syllable names for Viera. and Stjarna is the Norse word for star.

You could alter Gilernil a touch to look vaguely Vieraesc. Gelrnyl or Gilrnjl for example. or really go crazy and drop your vowels with. Gylrnl

Viera will also sometimes pick new names after being exiled (which every Viera player is. since Viera Do Not Leave the Wood. or, idk maybe their second generation exiles) So Gilernil could be from that. It's not so strange looking a name that i- a name lore fanatics would even blink.

as for the surname. you look Rava, so your surname before exile would have been village. And you're in luck because Ly'Vain almost fits in perfectly between the Dei-Ijla, Eruyt or Hyskaris. just drop the ' which aren't used by Viera forest names. Ly-Vain Or Lyvain. Or alter it further with Ly-Vehn or Lyvehn.
