Ahh, Aragorn, son of Arathorn, fearless warrior, and speaker of Elvish. The bridge between worlds and heir to the throne. Without him, things would have turned out much worse in The Lord of the Rings.

By his own account, he is called Elessar, the Elfstone, Dúnadan, and the heir of Isildur Elendil's son of Gondor. But he's also sometimes called this other alias — you know, the one he gave to himself so he could galavant around the kingdom acting emo.

What was Aragorn's finsta name?
