Cara Dregg is a pre-made Sim from the neighborhood of Isla Paradiso, available in The Sims 3: Island Paradise. She is the wife of Edward Dregg and is unemployed at the start of the game. Cara is a ghost, and her color indicates that she died by drowning. Edward also died by drowning. Since Edward is implied to be a pirate captain, an incident might have happened in one of their voyages, causing them to drown.
While her husband is featured in The Sims 2: Bon Voyage, it is unknown what happened to her.
