Erik's Despair - NWN Side Quest (Chapter 2)
Erik's Despair is a side quest that begins by speaking to Erik inside of Farmer Ingo's House on the South Road map. During your dialogue with Erik ask him if he has any available work for you and he'll ask you to retrieve his mother's brooch from Constance O'Deel who lives nearby.
You can find the house with Constance O'Deel in the southwestern portion of the South Road map. Pete O'Deel is patrolling around this building and he'll start the Peter and the Wolves side quest, if you want to pick that up while you're in the area too. Constance O'Deel is found inside of the building, speak with her and she'll be quite unreasonable with you.
Constance wants some gold for the brooch that she stole and won't give it to you unless you give her some gold or kill her. If you threaten her she'll immediately become hostile so don't take that route unless you want the Evil alignment points. You can bargain her down to a lower amount with a good enough Persuade skill.
Either way, once you've acquired the brooch from Constance you'll want to return to Erik and give it to him to complete the quest.
