I never liked llamas.
I will have to get my self a copy of that it sounds extremely interesting. I suppose since Caerwen was shunned for being mean then that would prove that Elmerf was not mean, since as far as I know he wasn`t not left to go guard some cave. Or of course it could of been some plot and he might have framed his sister for something so he could have Legolas to himself?
Anything is of course possible.
