Well, this IS an alternate timeline, so there's no reason the past couldn't be different from official lore. Besides, Just because the RACE is old, doesn't mean that that specific elf is old. I don't know how quickly NE's grow up, but for all I know, she could be twenty years old or something?
It's because they're furblogs, not furbolgs.
Night Elves can live to like 1000+ years. And they become an adult around 110-300 years. So if she was 20 years old she'd be like a toddler or something.

Alright, I consider myself lectured :) My point about the alternate timeline still stands though

Hello! Long time reader, first time poster. Let me just say, that I really enjoy the story so far.
There is just one thing bothering me, since Night elves are a pretty old race that implies that the Night elf girl was little a long time ago, before the Burning legion invaded Azeroth during the 3rd war again. Before that, the many Furbolg tribes were peaceful, non-violent and a friend to Night elves, only at the time of the war they became violent and aggressive because of the corruption that the demons spread. So I don't see the reason why the night elf girl would be scared there. And gloating over their kill? That doesn't seem like them at all.
