The Time Dimension is a dimension which is home to the Island of Time, where all of time in the Z Multiverse is observed and protected.
The Time Dimension is filled with paths to other times. It is believed by some that traveling through too much can result is the end of the Omniverse, although the Time Island is home to a man who fixes this problem whenever it is close to occurring.
The Time Dimension, aside from the Time Island, appears as though it is made of water. The Time Island appears as a giant island covered in huge temples. Each temple houses a Time Maiden, and there is a temple in the center of the island which houses the Time Sage, Ruton. Often, the Time Maidens will have an important purpose.
