The Grand Oak

The Grand Oak is a large talking sentient tree that lives in the Dalish forest. He is different from the other trees in that he is not naturally aggressive towards the player character, and that he can talk. For unknown reasons, he only talks in rhyme when speaking. He jokingly suggests that this might be because he was fused with the soul of a poet, and is thus, a poet tree. He does appear to be a little lonely, and his desire for companionship has led him to place tremendous value upon his acorn.

Involvement
He sends you on a quest to retrieve his acorn from the Mad Hermit. This can be done by trading either a book or a scarf in exchange for the acorn. The tree will reward you for returning his acorn by giving you some of his bark. Possessing this bark will allow you to go into the center of the Dalish forest. Also, you can chose to attack the tree to progress the Mad Hermit quest line.

Strategy
Fighting the tree can be avoided if one brings the tree back his acorn. Otherwise, I suppose fire arrows would be a good bet, since he's a tree after all.

Quotes
"Perhaps I am a poet tree"

Trivia
Clearly, this character is based off of the ents in Tolkien's Lord of the Rings Trilogy. However, unlike the ents, this tree rhymes and also does not appear to be nearly as old as the Ents are.
