i dont know about accuracy as far as the symbol goes but there are some powerful images there.

the funeral bier in itself

the way the the ancient symbol calls eyes to mind

Note the mountain in the left."his blood on the slopes of shayol guhl"..

The broken sword on teh ground at the base.

And finally the women presumably min aviendha and elayne dressed in mourning white

so may things there and thats at first glance. wow

if i had to take a guess i would say that the women would be nynave adn alivia. they are the ones supposed to help. we recall that alivia will help him die. tho i may be worng.....thats the beauty of a guess tho. sad to see the end but the reread will be worth it!
