Dragon Age: Origins

There are a total of nine party members in the game (not including DLC), and they are named as followed:

- Alistair (story related)
- Morrigan (story related)
- Dog (you name it, see below)
- Leliana (see below)
- Sten (see below)
- Wynne (see below)
- Oghren (story related, see below)
- Zevran (see below)
- Loghain (see below)

Several of these characters are story related and can't be missed. The rest however, require a little effort, just make sure not to kill them or turn them away.

If your origin is a Human Noble then you will automatically get the dog, however if you are anything else you need to complete a side-quest while in Ostagar. The kennel owner will have several dogs sick with taint, and will ask you to retrieve a certain flower from the wilds. Bring back one of the flowers (there are several) and you will get the dog after you complete Ostagar.

Leliana is located in the tavern in Lothering. Enter it, and she will automatically talk to you. Just make sure to accept her into your party when she asks. She can be missed if you leave Lothering before talking to her.

Sten is another one people usually miss. He is imprisoned in a cage in the town of Lothering. Speak to him about how he got there, and then go to the Reverend Mother in the Chantry and persuade her to release him. Once you release him, ask him to join your party. You must do this before leaving Lothering, otherwise you will miss your chance.

Wynne is located in the Circle Tower, which you will go to as part of the main story. Just make sure not to kill her when you first meet, and she should join your party after a short discussion.

You get Oghren while in Orzammar (Note: If you haven't been there yet, it is the cave in the uppper left of your map). He is a part of the story and no matter what you do, he cannot be missed. He will join right as you are heading into the Deep Roads.

Zevran is an assassin hired to kill you and will appear at random, normally after you have recruited one of the major allies. You will encounter him and his band while traveling. Survive his ambush and spare his life. Accept him into your party, when the choice comes up.

As for Loghain, you get him towards the end of the game. When you confront him at the Landsmeet, make sure to duel him and choose your main character for the fight. After you beat him, spare him, and then make the decision to turn him into a Grey Warden. By doing this Alistair will leave your party and Loghain will replace him.

What the above solution forget to mentions is that in order to recruit Loghain you MUST side with the Queen and you MUST choose to battle him with your PLAYER CHARACTER and choose to let Loghain become a Grey Warden by sparing his life.

Other than that, his/her solution is fine.

- For the dog, simply start a Human Noble origin story and you'll get him at the beginning. You can name him whatever you like.
- Alistair is story related. You get him at Ostagar. He joins your party after the first quest.
- Morrigan joins you once you're about to leave for Lothering. This is after you complete your first quest in Ostagar.
- Leliana is in a tavern in Lothering called Dane's Refuge. Once you talk to her, she'll automatically join your party. You want to get her early on as Lothering is taken over by the blight later in the game.
- Sten is found in a cage on a side of the wooden fence in the center of the Lothering village. You have to persuade Revered Mother in the large Chantry to give you the keys to the cage. Once he's out, you can recruit him.
left.
- Oghren joins you in Orzammar when you're working on A Paragon of Her Kind. During this mission, you'll be finding a new king for Orzammar. Oghren's a strong warrior and will help you through the tough journey through the Crossroads.
- Wynne is found in the Circle Tower at the beginning of the Circle of Mages quest line. After a short fight, ask her to join your party. She may turn against you at the end of these quests, but as long as you initially recruited her, she counts.
- Zevran will ambush you at random during the later part of the game. For me, it happened during the Arl of Redcliffe. He can very easily be found wandering around Denerim.
- Loghain is one of the game's chief antagonists who eventually sides with you in the Landsmeet. You have to choose to battle him in order to free him and recruit him. Once you win the battle, he'll turn into a Grey Warden and join your party.

Once you've recruited all of them, you'll unlock the achievement. The ones in Lothering are easy to miss. If you missed them on your first playthrough, you can come back and get them on your second one. For Loghain, you simply have to load up your save from Landsmeet and choose to fight him and turn him into a Grey Warden.
