According to the Sims Wiki, "There are two kinds of tomb lot assignments in Edit Town and Create a World, Tomb and Hidden Tomb. These assignments are locked from use outside of the The Sims 3: World Adventures sub-neighborhoods in-game. The tomb lot assignment generates a tomb map tag, and it attracts explorer NPCs. The lot assignment does not generate the moodlets players will see in tombs, these are instead generated by the tomb fogger tomb object."
