Dragon Age: Origins walkthrough

NEW AREA: Brecilian Forest
There’s a Great Bear here protecting a Longsword, as well as a few wolves. Don’t miss the Andraste’s Grace at the top of the map! Leliana will go nuts for it. Swiftrunner will meet you, and then you’ll have some Darkspawn to deal with, including an Ogre.

In a pile of rubble near where you fight the Ogre, you’ll find two gifts: an Ox Bone for your dog, and a Painted Skyball, which any party member will like. Soldier on through the forest, taking any loot you find.

After talking to the Lady of the Forest, you’ll need to get Zathrian. Don’t miss the shortcut to the upper level to the right of where you talk to her! You can choose to side with either Zathrian or the Lady of the Forest. There’s an Achievement/Trophy for both choices. You’ll only get Slayer if you convince the Lady to kill all the Elves back at camp. However, you should know that Leliana and Alistair side with the Werewolves; Morrigan, on the other hand, does not. Depending on your choice, you’ll fight one of two bosses: Zathrian or the Lady of the Forest (revealed as Witherfang).

BOSS: Witherfang
Your usual techniques for taking down groups will work fine, though funneling the wolves isn’t a great option in such a big room.

BOSS: Zathrian
Zathrian will summon a few trees to help him while he fires projectiles from a distance. You might try a Mana drain spell, or maybe a shield to protect yourself from his magic. Make sure you don’t kill him after the battle, though – Leliana won’t like it. He’ll end the curse for you, which will make everyone happy, especially Leliana. Travel back to the Dalish camp to finish this quest.
Congratulations! You’ve ended the Elf/Werewolf conflict.
