Players have requested more Wantia furniture from the Isle of Mara ever since that adventure pack was released. It may have taken quite a bit of time for those requests to be acted upon, but I suspect that most everyone will agree that these have definitely been worth the wait.
This 7-page page collection is located in only one small section of Mara. Spawns are pages ("!") in and around the House of Nurwin in the Village of Shin, and are visible only to carpenters. (This is the house off by itself over near the zone to Mystic Lake.) Yes, you read that right, a carpenter-only page collection quest. Why carpenter-only? Because the reward is for a level 60 carpenter-only recipe book chock full of the Wantia furniture recipes, entitled "Nurwin Family Secrets".
When you have collected all of the pages, turn them in at any collection quest NPC for your recipe book reward.
Recipes are level 60, using common tier 7 ingredients.
||Wantia Bamboo Cupboard
||Wantia Bamboo Stool
|Wantia Canopy Bed*
|Wantia End Table
||Wantia Ornate Vessel
||Wantia Round Table
|Wantia Simple Bed
*Note that the armoire and the canopy bed used to be quest rewards from one of the Village of Shin quests, but have been removed from the reward options.
Inside the house - table facing the middle doors of the house, on the floor to the left of that table, and one on the bamboo cupboard next to Kim Nurwin.
Just outside the house - next to the pot beside the middle doors, front and back corners of the right-hand-side of the house, front lawn on right side of the house, and against the back corner of the logs to the left of the house.
General area - at the base of the rock on the hill to the north of the house, two spots by the rocks at the shore of the pond, at the base of the tree just to the west of the Nurwin lumberjacks, and the rocks up the hill to the east of the house of Nurwin.
