Received from: Bann Teagan [Redcliffe - Chantry]
Description: You can officially start this quest when you get to [Redcliffe] (M27, 1). Approach the bridge where you'll have a chance to talk to Tomas (M27, 2). The next conversation will take place in [Redcliffe - Chantry] where you'll receive an update from Teagan (M27, 3). If you refuse the help in dealing with the undead you're going to be asked to leave the village. Otherwise you'll be allowed to assist in the preparations for the upcoming invasion.
Start off by going to [Redcliffe - Tavern] (M27, 6) and talk to barkeep Lloyd (M27, 7). Mention the undead during the conversation and listen to his reaction. Notice that you can convince him to join the defenders thanks to intimidation.
Now travel to [Redcliffe - Smithy] (M27, 8). You won't be able to enter the building right away, however there are a few solutions to this problem - you can use persuasion, intimidation, break the door or use a lockpick to open it. Once you're inside talk to the blacksmith Owen (M27, 9) and you'll find out that he'll help in the preparation if you promise to help him. If you decide to help his daughter you'll automatically trigger a side mission (Lost in the castle).
Make sure to go to [Redcliffe - Store] (M27, 13) and you'll find a couple of barrels. Click on the barrels to examine them more thoroughly. Your next stop is [Redcliffe - Dwyn's house] (M27, 14). Break open the door to gain access to this building and once you're inside talk to the dwarf Dwyn (M27, 15). You can convince him to join the battle using intimidation or you can attack him if he still refuses to help.
Once you've explored the village find Sir Perth (M27, 16) on the hill in the north-east and talk to him. During the conversation you should inform your ally about the oil found in the store. You can also offer your services and Perth will ask you to help the soldiers in receiving additional holy protection. Travel to [Redcliffe - Chantry] (M27, 12) and talk to Mother Hanna (M27, 17). You can get what you want if you use persuasion or intimidation. Hanna will promise to deliver "sacred" amulets to the troops. You can now return to Sir Perth and inform him about your successful attempt (don't forget to warn him that the amulets will be fake).
There's only one more thing for you left to do and that is to talk to Murdock (M27, 18) who can be found in the center of the village. This conversation may be a little longer if you've decided to recruit some of the villagers. End the conversation by confirming that you're ready to defend the village. This will automatically start a new quest - Attack at dawn.
