View source for Unification of Dimensions (Nature of)

==Inquiry==

The ending of Chrono Cross suggests that the dimensions were unified and the rift closed. Time, which has been divided, will be unified again now. Schala says time is unified but she doesn't say when it must be unified. This creates somewhat of a problem since Home and Another Worlds both had distinct histories that could not be simply merged due to differences; for instance, the Dragoons were alive in Another, and dead in Home. Which timeline is used in the Ideal Timeline, the world after the Chrono Cross unifies the dimensions?

Please note that the question of whether Chronopolis would still exist in the Sea of Eden is addressed at Salt for the Dead Sea.
