Way to unlock: Automatically, after you approach Caer Bronach.
Quest giver: - (M13,5)
This quest appears in your journal automatically, after you approach Caer Bronach in the central part of Crestwood (M13,5). It consists in recapturing the stronghold from highwaymen. This will allow you to obtain experience, Influence and Power points, but another purpose of this is to gain you access to the dam, which is required for the completion of the Still Waters side quest.
Note - I recommend that you complete this quest after you progress to level 12, at least. The opponents inside are quite demanding and you are going to fight their leader.
Head towards the stronghold's main entrance and destroy the gate in any way (e.g. with your melee weapons or offensive spells). Depending on your preferences, you can either walk into the first yard straight away, or defend outside of the keep, at the destroyed gate. You will have to kill Highwayman Foot Soldiers, but you should also watch out for Highwayman Archers on rooftops and Armored Mabari, which you'd better slow down before they manage to reach the weaker party members.
After you eliminate the first wave, start the linear walk across the keep. You will have to fight more opponents, of course - you need to be prepared to eliminate big groups of highwaymen and additional reinforcements (it is a good idea to set traps on their routes, e.g. explosive runes. Again, watch out while fighting the enemy archers and try to kill them in the first place). Also, remember to attack Highwayman Guardsmen from the side.
Take the stairs to the upper level (around, there is a Supply crate) and attack the last group of opponents (M13,5a). This fight will be joined by the Highwayman Chief, after a while. Make sure that the weaker party members avoid the boss's stronger melee attacks. Also, rely on the attacks with electricity, which the boss is vulnerable to. After you have defeated the Chief, loot his corpse, where you should find a legendary weapon (The Last Stand Maul).
You now only need to make seizing Caer Bronach official. Take the last stairs to the North-Western part of the fort. Find the interactive point here and press the appropriate key/button to set the Inquisition flag.
Note - since you have already seized the keep, you can now resume the Still Waters side quest.

- New side quest unlocked: Rift at Caer Bronach
- New Inquisition stronghold unlocked: Caer Bronach
- Experience (lots)
