Westly had shown a few screens of a Blood Elf (in Sadrith Mora IIRC), so perhaps Lyssia confused them with the released Noght Elves?
No, I don't think so, although anything is possible. I distinctly remember downloading them, but it was before I started keeping a library of mods, and although I tried it out, I didn't use for it long. I did find the Night Elves in my search already, though. I thought they were made by the same person, but that part I was probably mistaken on.
Actually, now that I think about it, I stumbled on the Blood Elf mod when I was pointed to the Night Elves in response to a totally different search in another Mod Detectives thread. That was a LONG time ago, though, and it doesn't look like the thread is around anymore.
