Howdy folks! I was interested in using my Viera character for rp but I had a question about their origins. I've read what I could about lore compilations but I thought I'd just ask so forgive me if this seems obvious! Are Viera found solely on the First or are there those who are native to the Source? Is it a case like the other races where they are found on both and just have a differing name? And if there are those who have lived on the Source, have they just been hidden from society so far? And if they are only found on the First, would it be a huge deal for an average, non-WOL character to be able to come to the Source? Thanks very much!
