Well, they can come back as anything. Life as an essence would be able to find its way into anything, after all. Perhaps another Aershaa is a possibility! Aershaa have their souls, their life-essence. Perhaps that is a possibility. Would be an awesome plot twist within the story. A nice little love story XD
Gos, you don't necessarily have to change the whole character. Just their race. The rest of it could be exactly the same, and she's just a very pale human instead of a vampire. Living in a deep forest might make that possible. Or, just a character that has the same name as another! Lots of possibilities.
As for that winged serpent character, I'll make sure you see him when I actually get him XD He'll be most awesome! I love taurs too. They are just so funkeh in their make-up. Getting the two bodies to mould together in a believable way, thats the fun part!
Nivan... just... eww. Nasty images >.o' As for staying on Gaia forever, this year will be my 5th year o_O Come October anyway. Not that long for this account, as I got hacked, but 5 years in all. Malhyanth is as old as Gaia itself.
