Memory Lane is a board for all sorts of flashback threads detailing events that take place before your character's present posts on Dragon Ball: Sparking. Memory Lane is specifically for group flashback threads. Solo flashback threads should be posted in the Solo Writing Board.
Threads in Memory Lane are all considered canon to the site story. Your characters' PLs are flexible in Memory Lane, but generally should not be exceptionally high. In addition, events in Memory Lane should not contradict present, canon events on site. In the case of a substantial contradiction, you will be asked to edit it to fit the present timeline.
Memory Lane threads do not receive XP, but will receive zeni automatically like normal threads. This is to keep threads in the main boards in the present time the main focus of the site- flashback threads are great for developing your story, but they should not make up the majority of your thread count. You do not have to post Memory Lane threads in Threads to Grade because of this.
In addition, Action Threads cannot be made in this board in any form.
Memory Lane can allow for characters who are presently on different planets or dimensions to thread in a flashback as well. Again, though, there must either be an already established reason for their past relations somewhere beforehand in your background, or an otherwise reasonable set of circumstances must be stated.
