Tomahna- This age is the introductory age to the game. Here you explore the home of Atrus and Catherine. There are some simple puzzles and plenty of eye candy. When you finish the level, you're given your task to recapture their evil sons and rescue their daughter whom they kidnapped.

Cascade- This age existed later in the game. Essentially it was to be a level that made substantial use of water puzzles, hence lots of waterfalls, pools, and lakes.
