The Missing Druids - NWN Side Quest (Chapter 2)
The Missing Druids is a side quest that begins by speaking with Archdruid Aawill in the Neverwinter Woods - Druid Encampment map. As you may have guessed already, for this quest you'll be tasked with locating 3 missing Druids and having them return to the Druid Encampment.
2 of the Druids you're looking for can be found in the Neverwinter Wood - Deep Woods map. One is in the Nymph home in the northeast portion of the map and the other is inside of a cave in the southeast portion of the map. Both of these Druids will need to be saved by you before you can speak with them. The last Druid, Bree, can be found in Setara's Home which is in the Neverwinter Wood - Heart of the Forest map.
Terari: You'll find Terari in the Nymph's Home which is part of the Neverwinter Wood - Deep Woods map. He's found in the southern room, simply talk to him and then set him free to complete this step.
Orlane: Orlane is found in the spider infested cave in the southeastern part of the Neverwinter Wood - Deep Woods map. Inside of this cave you'll find a room marked Feeding Chamber, this is where you'll find Orlane. Eliminate the Queen Spider in this room then interact with the Spiderweb Cocoon in the middle of the room to free Orlane.
Bree: Bree is found inside of Setara's House which you'll find in the Neverwinter Wood - Heart of the Forest map. In order to unlock the prison cell that holds Bree you'll need to get Setara's Key from Setara by either killing her or completing her easy side quest, The Witch's Mirror.
