The Necteaux family is mentioned, but does not appear in, The Sims 3: World Adventures. The family is referenced in both Champs Les Sims adventures, and the flavor text of The Necteaux nectar rack where they are referred to as a 'legendary nectar making family' and stated as the manufacturers of The Necteaux nectar Rack it's self.
The Necteaux nectar rack and presumably some valuable Nectar.
The actual home of Anastasia Necteaux is not identified in The Sims 3: World Adventures, however it is stated that both she and Admiral Landgrabb resided in Champs Les Sims. The Admiral's Estate, Chateau du Landgraab, is located east of the Champs Les Sims Nectary which has several The Necteaux nectar racks, and furnishings such as beds that seem to indicate that it once served as a residential lot.
- Anastasia Necteaux - Anastasia Necteaux's relationship to Jean Necteaux is unknown. Was she a descendent, or wife in the family? What is known is that Admiral Landgrabb attempted to have her killed, presumably so he could take credit for inventing Nectar. She was rescued by a man named James Vaughan though it is unstated if they pursued a relationship.
- Jean Necteaux - Jean Necteaux invented Nectar 6000 years before The Sims 3 and resided in Champs Les Sims, France.
