Artallas is a High Elf of Nargothrond and the older brother of Airendis, a High Elf captain of Beleriand. 

He has a calm demeanor that makes him look cold and detached. He loves feeling at peace and he enjoys attention, especially from the people he loves, while at the same time, he doesn't like the spotlight. Despite his present calm, when he was a  just child, Artallas used do impulsive things, like cutting his own hair with a knife simply because it got in his eyes.

He is rather opinionated, yet he keeps an open mind as he had had enough time to understand both himself and the world around him. He knows his flaws just as he knows his virtues, yet he believes that his general outlook on things makes him quite boring and not the best conversational partner.

He is cunning, pays attention to small details in someone’s behaviour, just as he pays attention to the changes in the wind or the behaviour of the beasts. He likes the world to be simple and believes most problems can be solved by listening before striking. Artallas’ greatest fear is nothingness.

He rarely takes things personally, he attaches to people and things very hard, but once that step was taken, there is no turning back for him. He has a strange sense of humour for a high elf, and gets rather flirty if encouraged or comfortable with his company. 

He is loyal, sticks to his promises, but he’s also impulsive - a trait he kept from his young years - and bothered by everything he does not understand about himself or the world around him. He loves to laugh, loves to hear and see people happy, and finds joy in the smallest of things.
