Birthright is an Act 1 companion quest for either Bethany Hawke or Carver Hawke in Dragon Age II. During this quest you'll be searching for your Grandfathers will, which could prove that the Amell estate belongs to your family.
In Act 1, stop in at Gamlen's house to hear Leandra and Gamlen argue about money and about Grandfather Amell's will. Gamlen will say that nothing was left for Leandra. He will also say that the will is still in the Amell estate vault, which is no longer accessible since slavers now own the estate. After this conversation, speak to Carver or Bethany and discuss how to break into the vault in order to initiate the quest
The underground passage into Amell estate cellar can be found outside of Anders's Clinic in northern part of Darktown. Once inside the passage, expect some resistance from various slaver guards. Right as you step through the first, rather short hallway from the entrance, the Codex entry: History of Kirkwall: Chapter 1 will be on your right, (although you will probably be attacked before you can retrieve it). Loot of various sorts can be found in the side rooms. In the storeroom you can find a gift for Hawke's sibling (for the quest Portrait of the Past or Family History) and Codex entry: The Amell Family.
In the side room just before the Anteroom you can find more loot and another codex entry, Codex entry: History of Kirkwall: Chapter 2.
In the final room before the vault, the party will face a slaver mage as well as various other enemies. Disable the trap (Simple) in the room with a rogue to make the fight easier. The key to the vault can be found on the mage's body, and the Codex entry: History of the Circle will be on the floor in the northeast part of the if you're looking at the map, ( southeast if you're coming through the doorway ), across from the stairs leading to the vault.
Enter the vault to pick up over 9 as well as Grandfather Amell's will. The chest containing the will also holds an armor upgrade for Carver/Bethany. You will gain (+15) approval from Bethany upon entering the vault.Heirloom Amell Protective Sigils

At this point, Carver or Bethany will ask to take the will back to Leandra immediately. Agreeing with the sibling will transport the party back to Gamlen's house.
Leandra will be pleased to find out that her parents did not die angry, and will try to petition with the Viscount to get the estate back.
A follow-up conversation with Bethany can be started after the quest and you can gain Bethany: friendship (+10) by choosing Diplomatic/Helpful dialogues or (+10) if choosing Aggressive/Direct dialogues. A Humorous second dialog, and Aggressive third dialog also results in (+10).
