Timeline 1 and 2.

So the hero revamp project will be based on two timelines, one called Timeline 1 that happens in dimension one and one called Timeline 2 that happens in dimension 2. Each features events that happen throughout the history and eras of certain heroes. If there was to be a book, Timeline One and Timeline Two would both be summaries of all the adventures that happen to the heroes and then the stories would derive from there.  I will release both series' timeline  at the same time.
The question is, which timeline is which? ( Which company does it take after?)
