Adding to the TimelineEdit
If you wish to add to the Timeline, simply follow the guidelines above the actual timeline.
Creating an Alternate Universe TimelineEdit
If you are creating a timeline for your alternate universe, you must create a page titled Timeline/<Insert Universe Name Here>. Then you must choose a center for your timeline, from which to gauge the years (Before Meteorite, After Meteorite). Try to choose an important event.
Then you can create your timeline. Try to follow the same format as the official timeline.
